Who should I tip?

Who should I tip?
            and HOW MUCH??!!.............................

  

     Many people find it confusing as to who to tip and how much. There are no real "rules" for tipping, and the etiquette of it really depends on the individual. Besides many different opinions on who and how much to tip, customs can also vary by countries.  Ask a dozen people when and how much they tip, and you'll get a dozen different answers. Although there are no set rules for tipping, here are some guidelines to help you understand who we should tip and how much they should receive. After browsing several different sites I was able to gather what the average tip should be.

Some points regarding tipping etiquette: Information provided by http://www.getrichslowly.org/blog/2006/10/12/basic-tips-on-tipping-how-much-and-to-whom/

• If you use a coupon or gift certificate, calculate your tip based on the total before discount.
• Tip above the norm if:
  • Service is exceptional,
  • You’ve been a burden, or
  • You are a regular client.
• Don’t tip if it’s not deserved. Poor service should not be rewarded.
• In some circumstances, if you offer an initial tip — especially a large initial tip — you’ll get better service.
• If you take up a restaurant table for a long time, tip extra.
• Tip discreetly.
• When in doubt, tip.
