I get semi-panic attacks if I know I can’t have access to a toilet if I really want to, and not in 2 hours’ time, but in 5 or 10 minutes’ time. That’s why I avoided taking inter-city buses before I purchased my car (which happened 6 years ago), and instead opted for trains (which were slower but had working toilets).

In other words asking grown-up people to just “keep it in” doesn’t work, just ask Tottenham player Eric Dier for the latest example (am on mobile, too lazy to link, but a quick web search should give you the whole story).
