I was on the third day of the Inca Trail at a campsite where showers were available. In order to have a shower you had to buy a ticket from a kiosk that also sold many other things (drinks, crisps, chocolate, beer etc). They had a sign up saying "Towels available to Rent" - perfectly fine until we realised that this sign was hung up over a display of sanitary towels!
Also, in Lima I was browsing through a menu and noticed that they had Pancakes "with Sweat" available!
