TIPPING and BARGAINING
TIPPING
Tipping practices are similar to most parts of the world.  Where no service charge is included, 10% is adequate.
BARGAINING TECHNIQUES
Bargaining is a way of life in Mombasa so, naturally, the prices you will first be offered may be higher than the amount the seller really expects.  
  • There are no certain rules about how much you can reduce the price by.
  • Do not feel embarrassed by offering less than you feel the article is worth.
  • Do not start by offering the price you eventually mean to pay, because the owner will not feel he has made a good deal.
  • Try aiming to reduce the price by two-thirds, so start even lower.
