Not the kind of insult or atmosphere anyone should have to put up with, and, further, the generally affluent people of Harvard and MIT, which the store was located right between, weren't accustomed to it.
I called this out in 2000, when I made Web page about assembling PCs, during the rise of Web ecommerce retail. https://www.neilvandyke.org/cheap-pc-2000/
> I actually spent a lot of time checking out the local vendors, but was generally dissatisfied, and used them only as a last resort. If you're in Cambridge, MA, USA, some vendors I looked at: PCs for Everyone (informative Web site, but long waits at their showroom, and they didn't have a floppy drive after I'd waited 30 minutes), MicroCenter (large superstore, mailorder generally has better prices, didn't have advertised CD-RW drives in stock, the three of the four things I bought there were somehow defective), BestBuy (very poor component selection, guards at the entryways), and CompUSA (smaller version of MicroCenter, guard at front door insists upon comparing every shopper's purchases to their receipt as they leave). So much for brick&mortar service.
> UPDATE 2018-12-10: MicroCenter brick&mortar has risen to the challenge, and is now my overall favorite source for PC parts.
