Siesta, even if open
many shops and cafés in Calella keep siesta between 12-14 but not two hours, just maybe a half hour or so. They keep every door open but it's still closed, so if it looks empty and "dead" then it is :D
Keep piece of paper-pay
A few beggers have copied papers in english that tell you about the begger's life and why you should feel sorry for him.. After a while, after giving out other papers to other tourist he will come back, and if you don't give the paper back you have to give him money, if you don't want to, give the paper back..
