The highest denomination notes are €500. They don't print new ones anymore, but there are still plenty in circulation.
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)?
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 »
I’ve long imagined someone walking in, handing over $300K or whatever in cash, and driving it out the secret car exit on the third floor.
The mall downtown has Rolls Royce, I assume you can drive that right down the escalator if you want.
