Because whenver someone is using it and another faucet or the toilet flushes in one of the other bathrooms, the water either gets scolding hot and you have to wait for 5 minutes for it to get back to a 'normal' temperature or it gets freezing cold and you have to wait 5 minutes.

Although i must admit, its funny as all hell if Gary annoys me before he takes a shower and i go around flushing the toilets and turning the facuets on LOL

Does this happen to anyone else when they are in the shower?
