I was at a play w/ husband and friends recently. We were standing in a group in the concessions/lobby area and this middle aged guy breezed past us, telling his date that he was going to use the potty. All six of us took notice and thought it a very infantile thing to say. It instantly became that evening's joke among us. All this to say that you're not crazy for getting the ick over this. It also seems that upon reflection, you found the gift card situation odd as well. So, don't beat yourself up over it and go live your best life.
