The only thing in my locker at work was nescafe Salted Caramel Mocha sachets. I made one right before my call and one of the ladies that is always quick with backhanded compliments or sly/cheeky comments that can sound really rude said something like "is that coffee?" and then another guy next to me joined in and said "is it? what is that?". I explained and she went "Oh that's like one of those meal in a mug more than coffee!". The guy then said "how many coffees do you have on the go!?" and I said well one is a bottle of water, one is a winter warmer and there's my coffee." He asked what a winter warmer was and I explained it's a squash you make with hot water and got the response from a third person of "THAT'S SO AMERICAN!"
All I could respond with was "Squash isn't American! This is literally made and sold IN THE UK! TO A UK TARGET AUDIENCE!" The second guy had then said "why would I want to drink a winter warmer? Why would I want warm squash?!" and I said Why would you drink mulled wine? Why would you drink mulled cider?? They then started banging on about the coffee and I said "It literally comes from a sachet! I didn't just go in and make this coffee myself! It's instant coffee! The same as what you'd have of a different flavour!"
My brain is in American mode. I actually thought you were talking about Squash (Like Calabaza, Butternut, Courgettes) and I was like "What the heck? Heated up squash in a mug?!"
Then my British brain woke up and said "She's talking about juice! REMEMBER SQUASH IS JUICE!!" and I sat here laughing like a crazy person for 5 minutes.
Yeah, that one woman you work with sounds like a right one! I don't know what they're on about! When I was a kid and had a sore throat, Hot Ribena or Vimto was just the thing!
In fact, I'd say those people you work with aren't British. They're Russian Spies.
