DD started potty training this week. We have a portable potty (one of those fold up things with a disposable liner). The other day we were in a gallery with no toilet on that floor and only access to the floor with toilets was via a lift. We'd just missed the lift (so about a 5 minute wait) when DD announced she needed the potty. We found a quiet, discreet corner and she used it there. Spotted by manager on CCTV who told us it was unacceptable behaviour. Presumably he'd rather she peed on the floor! Anyone else had this experience? What should we have done?
