Costco - Part 2

I just returned from a trip to costco to stock-up on huggies. I started my shopping trip the same way I start every shopping trip - with a purchase of a fountain diet coke. My sister-in-law assured me that costco has large cups. Unfortunately for me, the costco I go to only has the small cups you get with a hot dog. When I confidently asked for the large-size cup, the hair-net wearing apron-lady looked at me like I was crazy and slurred out, "we only have on size cup here." Okay. it is official: store with world's largest products has world's smallest drinks.
