Maybe things are different in Glasgow, but I've talked to many people with shelter experience in the U.S., and rarely heard anything good, mostly bad. And it all sounds quite similar to what Orwell wrote about shelters over 100 years ago... dangerous, prison-like places with rules, restrictions, and abuse. It's pretty much a guarantee that you'll experience violence and your belongings will get stolen or damaged, sometimes by the staff themselves.

Compare that to what's essentially minimal camping in the city, with no bears and plenty of quality food... You couldn't pay me enough to go to a shelter.
