Yep but this guy didn't choose randomly. All the stuff he chose is relatively expensive in Thailand and I suspect that was the sole motive behind his choices (especially with all those Ferrero Rochers).
I ate more candy and snacks than I care to admit in Thailand (where I spent six months in total), most from 7-11 (which are about 4x as frequent as Starbucks in major cities in the US are). My preference was for stuff I wasn't familiar with (mainly Thai brands, but lots of Japanese stuff commonly available too), which is all dirt-cheap compared to equivalent prices in the US.
Meanwhile, for stuff like what this guy stole, prices were easily 2-3x what you'd pay at a 7-11 here (and it's already a ripoff here). So equivalent to fancy chocolate that you buy (or steal) for special occasions or to give to your friends. Just like this guy.
