I run a full service restaurant and I put off accepting cc as long as I could (27 years)but finally relented and added cc about 18 months ago. It really did not increase my sales but greatly reduced my profit because of the cc costs. You will have the butthole who gets a cup of coffee and puts it on a cc. U have to sign an agreement to not limit the amount that can be put on a cc so u are screwed. The costs to me for the cc is unbelievable.
I recently added a concession trailer to out little business and I do not accept cc and will not add them because of the cost. I suggest that u take a real close look at the first bill u get from the cc provider and I think u may rethink accepting cc for a $2 hotdog
