The self-checkout at Aldi is a godsend. Way too many times I’ve been on my lunch break trying to buy a sandwich and snack, only for some old git to be using the time at the till to have a chinwag with the cashier!
By all means, have a chat with the cashier, but not when there’s a massive queue of people waiting behind you! Also, you know those shelves near the window with the sign saying “Pack here”? That’s not a suggestion. Pack your shopping away from the tills so people can keep buying stuff.
If your only job is to go home at night, clock in, go home, clock out again later. If you think about it, by deliberately not doing your job as a cop, fewer people are getting killed.
