Altogether, I've only had someone come to the table with a wireless card terminal once in the US. The rest of the time was either like I described or was a place like Denny's where it was expected to pay at the front. I mostly just use my chip and signature cards at restaurants now because of this (and also because DC's rewards aren't good enough to consistently deal with the hassle), even though chip-enabled restaurants are still pretty uncommon. I'd probably think differently if wireless terminals were more common or if we more consistently had to pay at the front.
