Reis Magos, Goa
The time when my sandals broke while I was visiting Reis Magos fort. There was no way of getting them fixed and I had to roam around the entire fort barefoot.
Luckily, there were no too rocky surfaces and I just got a couple scratches, nothing else! I probably had the most authentic 17th century-ish visit. At least that's what I tell myself in consolation.
Has something like that ever happened to you?
