If you are traveling and have not had a half decent meal for a while or are tired of making the trip to the supermarket every day for food...try out your local buffet, you get to sit and eat like a normal person, as well as score enough food to last you 2 or 3 days.
Bring in your small carry pack, and have a plastic bag in it...everytime you go up to the buffet, take a little to add to the bag...
Some suggested take-outs:
Jams and Butters
Salt and pepper
Cooked meat or Chicken (if you eat it within 24 hours less time if it really hot out)
Cakes and or cookies for a treat
All these things will tide you over for a day or 2 for sure.
So to break it down, you pay 10E or 10$ or 10P for a meal, and you end out getting 3 or 4 meals out of it...YEHA, thats about 2.50 for a full meal!!
Just so you know, the buffet place will frown upon you doing this, so I would say be discrete.
( This tip is for the budget trav'la, not you average joe in his home town resturant!)
