Example of use...
Tourists should always be careful with their money and bags in the city centre. When you visit a cafe, always place your bags where you can see them, otherwise it is possible that somebody will steal them. Obviously, if you leave your bags unattended whilst you pay for your drinks, or go the the toilets, anybody could steal them. Nowhere is completely safe, not even expensive restaurants.
