Growing up my mom was always an amazing tipper, leaving a 20% tip for almost every meal. When we started traveling abroad I noticed that her tipping patterns changed depending upon the country and so I asked her about it on our trip to an island. There she informed me that every country is different and that before leaving on vacation she always looked up the etiquette. Now in my own travels, this is something that I always do and I want to share this tip with you.
Reading through the graphic you will find that the United States and Canada have the highest tip percentages with 15-20%. This is quite a large amount when compared to China, Japan, and South Korea where there is no tipping, unless you have been given exceptional or luxurious service. While the info-graph does state that you only need to tip for bags in the United States, I always tip the bellhop $5 a bag. Also, if you are staying at an all-inclusive resort you should check for their tipping policies. At Disney World, their on-property resorts have very specific tipping guidelines for their staff, so make sure to do your research.
Hope that helps and as always, drop me a line. If you are traveling and want to know the tipping etiquette, comment below and I will let you know what info I have.
