That part isnt true though :D I dont really eat at fancy places, but i cant remember putting away my tray in a restaurant EVER :D Or even having a tray for that matter : D Maybe once or twice at some really cheap lunchplace in Malmö.
I would say go ahead if you have the chance, compared to many western countries it's a nice place to live, unless your like me and want to live in big cities and pay 80% of your wage to live in a shoebox :D
