Coca-diet-coke-a-cola

Ok, I've been on this major health-kick lately, and I totally get the whole attempt-to-eat-healthy thing.

However, while at lunch this week, standing in line at the fountain patiently waiting to fill my too-big-to-go-cup, I watched this woman alternate filling her cup with Coca-Cola and Diet Coke. Half-a-second under Diet Coke...half-a-second under Coca-Cola...Repeat. Does this strike anyone else as weird? Shouldn't it be more of an all-or-nothing approach?

Last time I was at Bajio, some guy bought, i mean stole, my shrimp tacos. I swear I'm the only person in the world who attracts such weird experiences with food...
