Will travel for toothpaste

I ran out of toothpaste a couple months ago, and since then I've been using the little free ones they've been giving me when I board business class.

I just got another one today. Thank god because I ran out last week and my teeth are starting to turn purple.

J/k of course. But seriously I did run out this morning so now I don't have to buy toothpaste for 5 more days. Yay!

I guess I have to change my flight to Argentina to line up with when I run out of toothpaste again? Engineering is all about efficiency right?
