Got milk?

I was in Chicago last week until Sunday for AIA/APA. While there, I tried doing what I always do, ordering milk at a restaurant. I'm used to people giving me a weird look, but this one was a new twist...

Me: I'd like a glass of milk, please.
Waiter: A glass of what?
Me: Milk.
Waiter: What kind?
Me: Whole or 2%.
Waiter: Oh, you mean milk! I don't think we have any. Let me go check.
2-3 minutes elapse before the waiter returns.
Waiter: I'm sorry, we don't have any milk. We have [he lists the different types of soda they have], water, and coffee. Would you like one of those?
Me: No thank you, I prefer milk.

Now, what is weird is that I had been in this same restaurant 2 days earlier and they had found some milk for me... What's up with that?

This isn't the first time recently that I haven't been able to get milk. Going to AAR/SBL in San Diego, I normally get milk on the airplane. They didn't have any this time. I've been flying for well over 20 years, and that was the first time I couldn't get milk, except for short little commuter flights that just hand out bottles of water.

I don't think the American Dairy Association's "Got Milk?" campaign worked very well...

Why milk? I don't know, I just prefer it. Debbie and I go through almost a gallon a day; she drinks skim, I drink 2%, almost a 1/2 gallon each per day. Maybe it is because we both have spent about 35 of our 50+ years in either Wisconsin or Minnesota? Or, maybe we just prefer it. It definitely is better for you than soda!
