What product can I sell..............?

Question

I work for a beverage co. we install and repair soda fountain machines at restaurants.
My question is since I go to a lot of restaurants there must be something I can sell the restaurant owner. I go to atleast 8 restaurants per week.
Do you have any ideas?
not restaurant insurance though , because I have tried that , it is a hard sell most restaurants already have that.
I dont't have to make alot of money just something that i can make a few extra dollars on the side.
We service anything from small mom & pop stores to major chains like Mcdonalds, Fancy places in beverly holes , bars and hotels.
There must be something I can sell.

oops! I meant beverly hills not holes.

Why not look at it backwards....Why dont you get businesses to pay you money...to give free napkins to restaraunts? These napkins will have the company's names on them..Sort of like...selling advertising...
