Very minor fuck up, but I thought I'd share it anyway.
First off, I'm in Australia, and tipping isn't a thing here. But some local businesses will have a tip jar on the counter.
I was at this bakery which I frequent a lot, and I'll tip some of the coins in change I get back in the jar. Today however, I get my $5.
50 change back - in a note and a 50c coin - and go to drop the coin in the jar. Instead I drop both the coin and the note in. I needed that $5 for a bus to get back home.
I didn't want to be the guy who reached into the tip jar with the cashier right in front of me to get my money back, so I just left. I walked for 30 minutes instead of a 10 minutes bus drive.
