I know you can say "Inecek Var" to stop a dolmuş but I´m sure I´ve had people say another phrase? Musait or something like this?  Any help...thank you

Hi, click on the link below and look at response 14

travelling by dolmuş

 Musait bir yerde inebilir miyim? (Can I get off at a convenient place?)

Musait bir yerde! (Somewhere suitable!)

Musait bir yerde indirir misiniz? (Will you let me get off somewhere convenient?)

Or you could just name the place where you want to get off:

´Yol ağzı lütfen´, ´Durakta lütfen´, ´Işıkları geçince´, ´Migros´ta lütfen´. etc.

"Kaptan, sağda inecek var" is funnier. 

 Not funny when you want to get off at the left

, then you are going to say "Kaptan, solda inecek var"

You may be obliged to get off by the window or driver door

 I thought that was regular procedure

If you are taking a dolmuş going to or coming from ODTÜ/METU, you can say Hocam

  yeah, thats the one the first thing that i realized when i began to study there...

say to him "dayı beni indirecenmi"

he should be a bit elder
