Feck me, you lot are acting like children. I would expect this on YD (a UK dive forum).
I would be more than happy to go on either trip, I just have problems with getting a US visa.
And, SLP, this is uncalled for....
And to forget to tip you cheap wanker!
I personally dispise the fact that a 15% tip is expected. It may well be part of the culture in the states, but, for me certainly, a tip is for good service, not ordinary service. On a $3000 trip, there is no way on earth I would be handing over $450, even for exceptional service. If the staff need the tips to survive, then the employer is not paying them enough. Tips are a bonus, not something to be expected from everybody that turns up.
And if I were on one of these trips, there would be myself and SWMBO, so a $900 tip? That's a fair few days diving in the Philippines for us.
