'I'm an American in the UK and there's 1 British custom I can't get my head around'

If you want something quick, tasty, and filling, you can't go wrong with a sandwich. There's an almost endless number of combinations, from fillings like cheese, salad, ham, chicken, tuna, and fish fingers, or something fancier like avocado or fresh crab, as well as the many different types of bread. But one American man who has lived in the UK has revealed a big difference between how we make our lunch favourite and how they do it over the pond. Zach Lincoln , originally from the USA , lived in the UK until recently, and regularly shares his insights into the differences in culture on social media. He recently posted a video on Instagram revealing he had been floored to learn one thing about how British people make sandwiches. The clip featured Zach looking baffled, the caption: "I just found this is normal here". "British people do not realise how weird this is," he said. "I just found out about this today and, I'm going to level with you, I don't think I'm ok with this. "I have come to appreciate many customs here in the UK, but this, I just don't know what to do with. It came to my attention after making my daughter a turkey sandwich. Well, it was a chicken sandwich actually. "And I posted about it [and] someone asked which type of butter that I use. I was like 'what do you mean butter?' "It was just mayonnaise, turkey, you know, maybe some cheese if they're feeling saucy, and it became a discussion, and I found out you guys all put butter on your sandwiches. Or many of you, I shouldn't say all." Looking aghast, he continued: "I have not been the same since finding that information out. Like, I understand it, intellectually, but like, I've never done it, and I don't know that I'm capable of doing it. "Like, there's part of me that wants to try it just to say I did but like, I don't, first of all, I don't eat meat, so I don't know what situation I would try it, like maybe a peanut butter and jelly?" People in the comments all said the same thing. One person said: "No butter is a CRIME." Another said: "If you tell us you also eat dry toast I am calling the police." And someone else wrote: "Bro we literally invented the sandwich." A different user said: "Sometimes, with *just* the right bread or roll, it's ONLY butter." But, replying to this, another countered: "I mean, we Americans definitely understand the value of butter on plain bread, but at that point, you can't call it a sandwich." Another explained the reason butter is used. They said: "The butter adds a layer of fat so that if you add salad of some kind (lettuce, tomatoes, cucumber) the moisture will not be able to travel beyond that layer and make the bread soggy. It is science." And someone else said: "Dude get yourself some cheese and onion crisps, a tiger loaf, and real butter. Cut some nice thick slices, slap a load of butter on, then put loads of crisps on and squash it flat and then eat. Thank me later." Another simply said: "A sandwich without butter is a sadwich."
