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.
