Ill be frank as well (junior dr here). They buy you lunch weekly, often for the whole establishment (your practice, the hospital, etc.). In the ye olde days they erherm..'sponsored' vacations for doctors to for example, Hawaii. It could be like a 1 week vacation, where they'd require you to spend half a day learning about their drug and going through their marketing spiel with you. In return they'd host your flights, accomodation and food (trust me the food is good).
