You can trivially make €500/mo as a beggar, but it's extremely time inefficient.

In other words, how much time you have per week?

[gcheong]

Is this based on your own experience? If so, what did you find most effective?

[mrbait]

No, it's based on rumours about some local old ladies' begging syndicate.

My point was about efficiency though.

[stefanos82]

I have around 10 hours per week, if that helps.

[brudgers]

That's about 40 hours a month so waiting tables would probably work.

Or Barrista.

Or mall security guard.

Or basically, an ordinary low wage job is the simplest thing that might work.

[qup]

Any job paying 12.50/hour with an amenable schedule meets the requirements.

A friend used to work part-time at KFC, roughly within your parameters.
