We took a few photos in Samara´s underground, when a passer-by started to shout at us and finally must have called the police.
In any case: we were held up when leaving the metro and passed 45 minutes in a police station. After recording all our details, passport number etc. we had to delete the pictures.
being part of the working group I could experience the missing protective equipment, dangerous working environment (e.g. loose electric wires at the place where we were supposed to empty buckets of water, etc.) but nobody bothers too much
also it is useful to have a good balance, not to break a single rib when falling down from rocking chairs while painting the ceiling or cleaning the windows etc :o)
If you have a bad day, better do not walk barefoot on the beach. It is a sad thing, that the locals leave broken glass there :( I tried to excuse them, that when they do it, usually they are too drunken to realize the guilt
