if you are approached with ANYONE with free scratchcards, tell them you're not interested and keep walking! if you accept one, it will ALWAYS be a WINNING ticket, you then have to go to the "office" to collect your prize. When you get there you are subjected to a high pressure 4-5 hour sales pitch on what is effectively a twist in timeshare!! at the end (after you have had to refuse any more- point blank!) you will be given a cheap bottle of cava or something claiming to be vodka. Best to just say no.
