HA! Did this embarrassing thing ever happen to you..? I just closed the overly-packed backpack packed with pabulum when the lady says nemnemneeem - you have no money on your card!! Simultaneously I was phone-less as I accidently left my phone at home when I went to the gym so blablabla I did get my precious food eventually but I also had do bike like a quasi-maniac to get home get money AND return before closing time (this was a short period of time). Now how stressful for being a nice afternoon!
