As an Instructor in a country that doesnt tip i know tips are a rarity, but when diving in florida i know better than to stiff the DM. What is standard practice on liveaboards? Does it depend on country like land based operations? I was researching liveaboard trips and saw on the Aurora Liveaboard inTerms and Conditions section the following: "Tips for Crew - Clients will pay onboard a service charge of 8 per night per person, this is an obligatory fee." !!! When paying 300 a night you think they could put 8 towards tip or just raise the price 8 and give it to the crew without telling the customer they are obligated to tip while onboard. Ive seen other sites recommend 10-12 euro per day but it wasnt required. Personally, if i have a lousy time i dont want to tip and if i have a great time i want to leave a big tip, and i may want more of the tip to go to the DM than the others. Whats your take?
