The return of ’small’

I’m sitting at a Wendy’s in Mississippi,

where someone finally figured out that having Medium, Large, and Extra-large doesn’t make any sense. What’s the smallest size now? Small (but it turns out it’s the old medium). At least it makes sense with 3 choices. I really see this as evidence of the ‘enlargement’ of the US. Twenty ounces is a lot of soda, I guess the ice makes up for it.
