Funny that you guys are talking about that because I came to post about a similar thing:

people who're standing in line at the checkout at the supermarket (or I guess anywhere) when it's busy, and stand there for like three minutes in line with their shit on the conveyor belt then another minute while all their stuff gets scanned and then act all fucking surprised about having to pay for their shit in that they've made no effort to get their wallet out of their bag let alone some money out of their wallet before the cashier is finished and tells them what's up. I just wanna go home and make dinner
