Subway

Yet another English business operated by people who never got the memo that Scotland is part of the United Kingdom. They only accept cash — no cards — and they refused to accept my fiver (fiver, as in British Pounds Sterling) because it was issued by the bank of Scotland. I explained to them that the note was in Pounds Sterling, the same currency as English-​issued pounds, just issued in Scotland, but they insisted that they were not *allowed* to accept it. So either they’re very dim, or their manager has instructed them that Scots’ money is no good at their establishment. Either way, fail pile of fail.

Much as I love the Subway concept there are better examples of how it is down than this one.
If you have never been to one the idea is that you pick the type of roll you want from a selection of breads, then opt for 6 inch or footlong. You then choose what meat filling you want (or non-​meant, calm down veggies.) with the option of cheese. There is a big selection, some hot, some cold. Once you have down that you can add from any number of toppings to make your sandwich a cracker, finally adding in your choice or sauce from another wide selection.
In theory therefore, unless you don’t know your own tastebuds you will always get a great sandwich.
The food isn’t so much the problem here as much as the fact that the seating area is small, not very well laid out, and often a bit on the tatty side which means it isn’t the nicest place to sit down and enjoy that sandwich.
