No offence People With Learning Difficulties, but I think it's fair to say there are times when everyday things seem almost impossible.
I'd just like to point out that one of those times is ordering a sandwich when there's five different types of bread and over 20 individual salad options.
Now I'm not saying 'don't let people with learning difficulties go into Subway.' All I am saying is, "Marks and Spencer sandwiches are quite nice. And they're pre-packaged, which is handy…"
