Sticker lady in Canada

How it works:

• Otherwise known as Catherine Katie Herbert, the sticker lady is a fixture for decades on Yonge Street.
• She first compliments your good looks and then offers a smiley face sticker. If you take it, payment will be demanded.
• If you reject, she will claim that this is for a charity, which can be for the homeless or the sick.

Places to beware:

• Toronto: Yonge Street, City Hall

What to do:

• Decline.
