Thai Airways flights from Ho Chi Minh City to Frankfurt am Main Airport (SGN - FRA)

The Crew was really helpfull and nice, A/C was coold for me but for others i think it is ok and the food not bad and not that good. The Thailand Airways employee at the Indera Ghandi Airport " Indian guy " was very bad he hold us for 2 hrs and then he run away letting us the last people at the transit counter and couse us to be so late and about to lose our flight to Bangkok, for nothing. He asked us of we have a retuern ticket, and we told him that we have not because we are traveling for treatment, and then he asked us to wait for 2 minutes, After we wait for a long time he just run away, And after we asked the lady she said ok no need now for return tickets and she gave us the accsess to the gate.
