It’s not just bis. Gays do it to. I found out from Reddit gay subs that I should be a fast walker. Apparently gay people all walk fast. Not something I’ve ever noticed.
Returning trolleys was the norm in England during the 90s. I dunno what the fuck happened for everyone to suddenly start refusing to return them. Maybe the employment of trolley collectors made people lazy?
Winds me up though. I always return them and make sure to return any nearby ones.
