Unimportant tangent: Is checking receipts and looking into bags really legal in the (I would assume) US? It isn't in Germany and if employees hold you against your will they better be damn sure that you actually stole something or they are in serious trouble (as in: possibly going to jail trouble).
" It isn't in Germany and if employees hold you against your will they better be damn sure that you actually stole something or they are in serious trouble (as in: possibly going to jail trouble)."
The USA (or least New York state) has laws against false imprisonment, false arrest, and unlawful detainment.
That’s just a risk a store owner has to bear.
