I don't remember actually doing tips as a percentage back when I lived in Latvia, it was usually that you took the bills and left any coins, maybe added some on top if there weren't many.
So probably 10% at most but still basically what I made per hour as a warehouse worker
Damn, people need to lighten up here, OP posts an obvious joke and half of the comments are just "mUh iNdUsTrIaL SaFeTy"
