Moving - have you arranged for amenities?

Hello dear colleagues,

we are currently considering whether to provide the moving team with snacks, drinks, etc.
How did you handle that? Mettbrötchen, coffee, cola, Fanta... blah blah blah...?
Or do you say they get their money (the company) and a tip is enough.

The full program with me:
I put out drinks because it was almost 35° Celsius in the shade that day.
At noon there were sandwiches. You want to eat something yourself (and the children) that day too, amidst all the stress.
There was a little extra tip.

During my moves, I provided drinks twice and then gave a tip. But each time it was done in 3 hours.
During one move, I also had friends help. We finished in 1.5 hours and then there was no tip.

The move took the whole day, I provided a midday snack (I asked what they wanted - Döner - they were all Arabs). And kept putting out drinks constantly. They didn’t touch the cola and coffee, only water and very little. They also didn’t use any of our toilets even once (). GD

moved with company,
still and sparkling water, coffee, sandwiches,
no damages caused,
100€ tip, 4 men 10 hours

How does it currently work under Corona conditions? I read that the moving helpers have to be registered, is there any truth to that?
