Is a business lying about a broken card machine an illegal bait and switch?

Our b&b owner wants to force us to pay cash so he is pretending his credit card machine is broken.

Our church used to visit Vietnamese Pho noodle restaurants that told us they accepted credit card and after we were done eating they would lie and tell us their credit card machine was broken, because if they do not accept credit card they can avoid reporting their full income to the government and get away with paying lower taxes.
