We live off chips in Britain @bengy - it's out staple diet. Wake up in the morning Toast ❌ Cereals ❌ Chips ✔️ then it's chips for lunch, chips for evening meal and then after an evening out visiting social places of musical interest - it's 2am chips. Sometimes we vary our diet with beans on toast.
It's a shame about the coffee, quite often the problem isn't the machine or even the coffee beans generally - it's nobody does a really good job of showing the staff how to combine them to make a good drink.
Ha ha, baked beans is the other thing that we just don't get! I was expecting mushy peas with everything...
I know what you mean with the coffee training. Too many places think a decent expensive machine and some beans will work magic. I've had way too many coffees that are scalding hot or the milk has been burnt... Leaves a foul taste in the mouth.
