For the last 9 or so months I've been working at Blockbuster at my student town. It's quite possibly the perfect job for myself; I get paid to talk endlessly about games and films and these people pay me for it. In that time, I've gone through loads of training to basically become a reserve manager on duty, so basically I have to sort stuff out myself and can't rely on anyone else.
This evening, I had my first ever nasty customer. I've been incredibly lucky up until this point, with other members of staff getting abuse off customers on the phone or being swore at over the counters (always over late fees, people always refuse to pay and try anything to get past it). That's what the customer disputed over with me today, a measly £3 balance from 3 films they'd rented in April and kept an extra night, resulting in a £1 charge per film. I even was able to tell them the film titles and the exact time they were checked into our system, but they still disputed. They decided to continue the sale and pay the balance so they could rent again (as they seemed to think that talking to the manager would result ina refund of their late fees, ha), but with them being such nasty buggars I didn't feel like being nice, so I made a point of putting their 2 99p (keep for 1 night) films through for just that, 1 night, when they also rented 3 new release rentals, so I could of been nice and put them all through for 3.
When they found out that they'd have to return the 99p ones the next day, and the other 3 after 3 nights, they point blank refused sale, called me all sorts, were being really dismissive with her husband just saying 'just leave it. let's go. If they're going to mess us around then just don't even bother'. She's now returning tomorrow to speak to the manager, which I cannot wait to see as I'm working aswell, my manager's even meaner over this than myself.
tl;dr. Ever had abusive/nasty customers whilst at work? and how did you handle it?
