Oops, I forgot about the briefcases full of unmarked €500 notes they must have their assistants lug around.
So, is the default tip 500 (highest available) or 200 (highest you will ordinarily be given in a bank) or 100 (highest most people usually have on hand)?
At the time I lived there, tipping 500 for holding the door was not uncommon and half expected.
You’re joking about the briefcases, but a friend of mine had a group of bodyguards swarm the $LUXURY_SPORTS_CAR dealership he was working at, followed by the customer who bought a car cash - as in « literal cash from a suitcase »
