I hope I tipped enough

I hate this part did I do enough.
I've never used a moving company before.
We had 5 guys and a big truck. They did amazing. Got everything in one trip and even put the boxes in the room we wanted. Didn't damage anything and got done early.

So I gave them 100$ for the tip. 20 each.

Plus I had a cooler full of water, Gatorade, Powerade, lemonade, juices, tea and soda pop. Plus I had snacks for everyone. I let them keep the soda pop because nobody in our house drinks it.

They seemed grateful but I don't know. It was really hot and they worked really hard and fast.
