The one thing I learned to do in Philippines, is NEVER give pesos to streetkids - why? Simple - it will encourage more and more to do the same.
Its a fair point Rob, I rarely do it, my point is simple, in that I dont mind personaly giving out the odd 5p peiece here and there, only if I feel like it, as you quite rightly say, you can be deluged by them.

Boy its so hot tonight over here in Essex, I actually sat outside the house on my garden bench, as its so hot, and let the cool breeze get to me, geeeeeze its like the barangays tonight.
