I worked at Blockbuster for a while and the amount of people who come to the check out line on their phone was amazing! They figure all they're doing is giving you money and getting out. They forget that we also tell you when the movie is due. Every time we had one of these lovely customers we made a note on the account "was talking on cell phone" and the date. Without fail they'd come in again and try to argue that they shouldn't have to pay the late fee b/c no one told them when the movie was due back. We'd kindly remind them the last time they were in they had an important phone call and couldn't be bothered.
