I feel like a fool..

I rented a tent for this weekend. One guy came, set it up, brought out tables and chairs..All by himself.
DS started whining, I signed the papers and he left. I didn't tip him. I feel so bad, dumb, stupid..etc.
They have to come back to take the stuff down early next week. I am praying it's the same guy.
What would you do in this situation? Call and ask for his name? Send something to the company? or just wait until next week and see if it's him?
I feel so bad!

I would call and ask his name. When they come to take it down, just have an envelope ready for him.

Call the company, explain what happened & ask if the same guy can be scheduled for the pick up.
