I'll let you know when I encounter one in person.
By the way, I never said I would frequent a place that didn't take cash. I just know (from my wife's experience in banking) that it is preferable if the establishment is small and offers a choice of cash or charge, 99% of the time we will use cash.
Hmmm, that didn't come out the way I wanted it to. I think "would" should be "wouldn't". Three negatives in a sentence. Sheesh!
There are a number of cashless businesses here in Houston. They are typically small businesses who do it primarily to deter robberies, burglaries, and employee theft. They also do it because handling, counting, and banking cash is an expensive nuisance, particularly when most of your customers primarily pay with plastic anyway.
Those businesses should be allowed to use their own business judgment and make their own decisions, and not have it forced on them by the government.
