I always butter my sandwich..no matter if I put something spicy or something sweet on the sandwich. I also need butter even if I put Mayo on my sandwich.

Yes!

I have genuinely never heard of people buttering their sandwiches.

I use a little bit of mayo.

That's a thing?

Sounds disgusting. I would never butter sandwiches, just mayo.

Ew butter is disgusting

Butter makes EVERYTHING better.

Yes, if I'm topping the sandwich with something dry (ie: a slice of cheese, ham, etc) but if I'm topping the sandwich with something spreadable, then no

People butter sandwiches that aren't grilled cheeses?

No that sounds nasty. You don't need butter on there if you're also putting on mayo or mustard or whatever, that's just overkill I don't need to be clogging my arteries with even more butter.

Mayo is just as disgusting and bad for you

People butter their sandwiches?
This

No only toast and maybe garlic bread deserves to be buttered

I've always hated butter

Usually only on a sandwich that's just meat and cheese. Cold butter (well, I Can't Believe It's Not Butter) adds a nice crisp taste

Ew at you guys using mayo I hope you mean Miracle Whip.

Only when making grilled cheese.

I had no idea people buttered sandwiches...
