How many of yall ever pee in public (discreetly)...so today I had pee and I could not hold

It's freezing cold outside, expecting a blizzard and had to pee; me and hubby went to pick my mom up from work to take her home, while waiting I had to pee and ran between 2 cars in the parking lot and pee (such a relief. ..omg)....come back in the truck and hubby is like..."you pee in public"...in funny tone, like it was disgusting. ..I'm like ...are you serious?...we get home and he's like don't do that again....wtf. ...tell me folks is he over reacting
