Travel 'savings tips' Post No. 2

On the road:

1# In many places at backpacker hostels, a double room is cheaper
     than a single room or even a dorm bed. If you share it with a friend.

2# When eating in a restaurant with fellow travellers,
      they will always say, "Just pay in what you've had."
      or they also like saying, "Oh, we'll just split the bill at the end."

    Fact: This just sounds good, but does not really work.
    E.g:-You had 2 beers and someone else had 2 bottles of wine.
        -Many people forget what they had, so they put in less.
        -Most don't consider the tip at the end for the waiter.
        -Many get drunk and even leave without paying.

    To avoid all this, I pay as you go or have a separate bill.
