Basically I've had my account at the local BlockBuster since shortly before the dawn of time, or shortly after they opened the one in town nearly ten years back.
Now granted, I'm not a sick movie zealot renting every day, but I do visit enough that several of the staff know me by my name as soon as I walk in the door.
I stopped renting VHS a year ago, and now I pretty much only buy DVD's as renting DVD's are almost a waste. $5 to rent, $15 to buy. If I plan to watch it more than once, might as well buy it. At least then I can lend it out.
So, after buying about 8 DVD's over a six week period this spring, I got a hate letter from Blockbuster saying that unless I paid the money I owed to them immediately, there might be an "accident." The first paragraph still said they wanted me back (uhm, I never left), so that was nice.
Even though I had been using the 'BlockBuster Easy Payment Plan" <tm> of theirs (using my change and applying it to the account when I bought something), and all my DVD purchases were going on my account record, and I even got on the spiffy "Blockbuster Rewards Program" thingy, you'd think that one of these actions would have said "hey, let's not push him down the stairs."
Now technically, one could argue there were in the right to go with the hard line "Pay us in 10 days or else!" but that is hardly a way to treat a customer that in theory is a good customer.
At least when I'm rude to people, they deserve it.
