Hi! I was wondering the etiquette of tipping the Limo driver from Happy Limo for our airport transfers. I will be tipping 20% as long as the service deserves it, but my question is, do I tip the full 20% after the first leg? Split it up 10% and 10% or all at the end? Do they usually send the same driver? Thanks for your help! I have been a lurker for years but never posted, you are all WONDERFUL!:
