Express lane again...

Here's another grocery store story.  Can you stand it?

I was in the express lane at the local mega/super/stuff mart and the guy in front of me had 20 boxes of cereal -- each one different.

I know you're shocked.

1.  What was he doing in the express lane with what was obviously over 12 items?

2.  Who spends the time picking out 20 different types of cereal?

3.  Who eats 20 different types of cereal?

and most shocking of course.

4.  Why didn't he have any milk?  Does he have a lactose intolerant gerbil?

[I will also add here for Phi's benefit, he didn't have a single coupon]
