Tim Hortons

Every time I go to 1750 Plessis Tim Hortons there is always 3 slits and the bottom of the cup and then it leaks all over, I've started checking every time I get one and there is ALWAYS a hole in it. I tell the worker and they either re make it or put a double cup on it but they never seem to do anything about it. I've been to other Tims in my area and they don't have this problem.
