My round ranges from the town I live in, to about an hours drive away. I know from a profit point of view, I should try to replace my further away stuff with work closer, but I like the variety, and I get on well with most of my customers, well the ones that I see anyway.
As for eating, very rarely would I buy food while I am working. I don't stop for more than half an hour for dinner, often just 20 minutes, and, too expensive!.
I generally have a sandwich (boring sandwiches are created by boring people Mr Milton, try and be a bit more imaginative with the fillings, and even bread type!), sometimes a wrap.
