Background: I worked at 2 CompUSA's - Houston,TX & Denver,CO - and I worked 3 different positions - Merchandiser (Stocker), Sales (Accessories), and Sales (Networking).
First, why would you expect someone to honor a warranty after the time has expired? Consider it bad luck that your item broke shortly after the 30 days. Would you expect McDonalds to serve you breakfast at 10:45 when they stop at 10:30? No, because if they did someone else would complain about not being given the same service and we would probably be sued. Side note ? my manager probably would have taken care of you, he liked making people happy.
Second, yes we did try to rally the customers around 8:45PM. After the last customer leaves we can begin to "close down". For the Accessories and Networking sections this involved restocking all products in your area, "facing" all products (bringing them to the front of the shelves), re-tagging and replacing missing tags with price updates, cleaning your section, and having the manager walk your section. The Tech Shop, Communications (phones/cameras/mp3,GPS,PDAs), Hardware (Complete PC packages & notebooks), Mac, Home A/V, Warehouse, and Cashiers all had similar but different closing procedures including shutting down all equipment. Generally this took experienced people about a half hour on a -good- day (light foot traffic) to a couple hours on a bad day (Black Tuesday for example). Not to mention the cleaning crew which comes in at a certain time, about 9:15PM and begins to empty trash cans, mop, vacuum, and buff the floors, office and warehouse.
There were about 10-20 staff members on hand when our store closed. The company pays about 2.50/15 minutes on average for each staff member (not including managers). That's $22.50-45 a night, $157.5-315 a week, $630-1260 a month, $7560-15,120 a year - FOR ONE STORE. Not including the costs for the extra electricity, manager?s pay, etc. I realize these numbers aren?t entirely plausible but they illustrate my point. From a business stand point, I would want your ass out of my store at 9PM too. From a workers standpoint, I would like to go home to my gf/bf/friends/family/homework/etc. as soon as possible. I doubt there is any reason you couldn't come back the next day or later that week. If you know what you need, find it, buy it, and leave. If you?re still speaking with a sales person - that's okay, we want you to be happy with your purchase and get you what you need. Please don't be so inconsiderate as to assume that anyone should accommodate you so that you may browse before we close without purchasing anything. Best Buy has a similar PA announcement when the store is closing and I?ve always made sure I? finished before 9 because it?s unfair to so many people for me not to.
Third, I agree with what you mentioned about their prices and selection of products. For the most part, the selection was awful ? off brand, lame models, too few choices, etc. and the prices were TERRIBLE. I made quite a few purchases when I worked there only because of my employee discount. USB Cables costs the store about $3ea. and were sold for 19.99! Ugh, I hated the pricing and selection. Every once in a while though, a good deal was offered.
Fourth, the employees there were terrible. Most had no idea about what they were selling, enough perhaps to fool a consumer. Few knew what they were talking about but used their position for evil - confusing the consumer, tricking them into purchasing more than they should, up-selling them on stuff that provided little to no benefit. One guy used to brag everyday in the break room about how much commission he made lying to people about the products. When we made a sale we were told to ?tag? the item (put a sticker on it with our ID #) or, on large sales, walk them to the register ? they required this to keep track of how many customers were ?helped? by sales people. Also, this was how your commission was traced to you. I barely tagged anything and rarely ever without asking the customer directly if it was okay that I make a commission on their purchase. I wanted to actually help my customers.
Lastly, I?m not putting too much stock into the livelihood of the CompUSA brand. TigerDirect blows. If they were more like a Directron (www.directron.com), or a brick-and-mortar version of Newegg, then might survive.
