My local burger shop offers a deal with burger, chips and soft drink, cheaper than you can buy a burger and chips.
So I get the deal, and look through the fridge, and every can of drink is loaded with sugar and phosphoric acid and most have caffeine.
No thanks.
It was amusing to watch the staff trying to grasp the concept that I was actually
not taking a drink at all. ... but ... but ... it's free!
And their burgers were crap and the chips poorly cooked.
