I haven't seen any Turkish above so with apologies for the inevitable misspellings...

Good morning= gun aydin

Goodbye (if you are leaving)Allahas marladik (pronounced alas marladuk)

And the other person replies Gule gule (pronounced gulay guleh)

This is all with a Cypriot accent!

CamiSu (who dropped the e because in Turkish it came out Su-ee)
