I’ve been waiting for a whole week to make it fun... and that’s what happened.)
I stand in the subway and wait for the train. A guy approaches a nearby machine to throw money on the phone. It takes a number - on the screen, of course, it is displayed with huge numbers and stuck in the 500p machine. I get the phone at this time and send the following plan SMS to this number for the last money:
“Thank you for giving us 500r for a beer. by admin :)"
You could see his face 😉
