I had very unpleasant and sad experience at one of the sport chain store on Croatian coast when I wanted to buy fishing rod for my child. I was in the store before end of working time, but when I got to the counter supposedly this working time was over. Shop personnel start complaining that they have now problem to issue invoice. Another employee came and said that she has a way to issue invoice, but shop manager told her not to do it. Instead, they called police, and police nailed me to the floor, broke my nose, handcuffed me and took me in a squad car to the station in front of my crying children!
In police station I was told they will keep me till the morning with my children scared in the car if I do not make a statement which didn't state that police worked in interest of chain store rather than me as civilian, and that they tried to falsely accuse me if not giving my ID.
My question is, was the shop obliged by the law to issue invoice and was my rights violated?
