I've ranted a fair bit in the past about portion sizes in America, and how they've inflated over the years so that now people think ridiculously-large meals are perfectly normal. I had a great example of it tonight at Arby's when I heard this conversation:
Customer (staring at menu): Do you still have the Giant? Cashier: It's now the medium Customer: Ah, OK. (Stares at menu some more.) I'll have a large roast beef.
Both sides of the conversation had a beautiful yet horrifying irony.
