Just a word of caution to those of you approached by monks for donations while walking along clark quay river. I've seen them almost everyday walking up and down the river for the past couple of weeks. They'll start by offering you a "blessed" buddha card/photo and then ask for some donation in return. You sign on book when giving them the money. These "monks" were highlighted in the newspaper almost a year back as cons.
They tend to approach tourist and westerners. Do beware.
