Is Tim Horton’s trying to scam us??

Is Canada’s favourite coffee place Tim Horton’s using sorcery to trick us into thinking that we’re actually getting more coffee in an Extra Large cup compared to the Large?
Facebook user Bryan Isaac Vaillancourt seems to thinks so.
He posted a video yesterday where he fills up a large Tim’s cup with water and then pours the water into the Extra Large cup. The results clearly show that you only get a sip or two more coffee in the extra large cup.

I must try this for myself.
