Can't remember the last time either of us bought a coffee out. We may have bought one each from a motorway service station last year I suppose, or it could have been the year before?
We have a take-away (either a chinese or fish & chips) maybe 2 or 3 times per year.
If we're having a day out or a few days away, then we'll sometimes have a "meal deal" for lunch on the road, from a supermarket or Greggs, or sometimes a McD, KFC or Burger King for lunch, where we'll have a soft drink included, or if in a town, probably more likely a chip butty from a chippy!
But usually, we'll take drinks/snacks with us on days out and for journeys, etc., i.e. a flask of coffee, some multipack bottles of water and crisps, a few pieces of fruit, and maybe a couple of home made sandwiches.
I just can't bear to pay for things I could easily and cheaply make at home and take with us.
