Small?

I was a little surprised today when I thought id pop into MacD’s and pickup a fat-packed breakfast to get me going for the day. I didnt know what to think when the fast food attendant handed me what was supposed to be my drink!? I swear the last time I had MacBreakfast the cups where twice as large!
My hands aren’t that big, and I didn’t ask for "small" meal, I’m assuming it is. I always thought you received the regular meal by default? Oh well, thirst quenching 3 mouthfuls will have to do :(
