Working under the table?

Hi there , i am a 33yr old male who wants to just enjoy europe and work a little here and there to keep the money flowin. I have heard stories ( maybe urban myths ) that it is easy to get jobs for a few day or a week here and there for cash. Any one have any experiances or tips on this.

I checked with my husband regarding your query with respect to the UK. He did not know what "under the table" but when I explained he said that in the UK that's called "cash in hand". We think there could be a possibility of such work ... may be brick laying?

Sorry I'm not much help.

It's possible but HARD, because of all the crackdown on illegal workers. If you find anything useful that's not illegal or immoral or degrading please tell me too!!
