R22DRIVER is correct. For the heli world it is as follows:
"PPL - 1 bar" This will the cheapest Bar in town where all the other new PPL's will hang out and discuss ways of earning more money to complete CPL.
"CPL - 2 Bars" The CPL will go to at least 2 Bars or more to tell anyone who will listen that he/she is a Commercial Helicopter pilot.
"CFI/II - 3 Bars" The CPL with some experience and an instructors rating has now moved back to the cheap Bar to impress the PPL's and save money for turbine endorsement.
"ATPL - 4 Bars" The ATPL will be found in any number of Bars (at least 4 in 1 night) reliving the glory days of his youth/past flying experiences/overseas postings/woman from said trips, and the fact that he is a helicopter pilot to anyone standing nearby.
