CLUELESS ABOUT REGULATIONS

WAS TRAVELLING TO HO CHI MINH CITY, VIETNAM FROM MUMBAI, INDIA, VIA BANGKOK, THAILAND. VIETNAM HAS A SYSTEM OF VISA ON ARRIVAL. WAS NOT ALLOWED TO BOARD THE FLIGHT BECAUSE I DID NOT HAVE A RETURN TICKET. VERY STRANGE, BECAUSE ON SEVERAL OCCASIONS IN THE PAST I HAVE TRAVELLED THE SAME WAY - EACH TIME ON A ONE WAY TICKET, BECAUSE MY RETURN DATE IS NEVER CERTAIN. WAS MADE TO PAY THROUGH MY NOSE FOR RETURN TICKETS I WAS FORCED TO PURCHASE FOR MYSLF AND MT WIFE AT THE AIRPORT ITSELF. <br> <br> WHAT IS MORE STRANGE IS THAT MY FRIEND, TRAVELLING ON THE VERY SAME NIGHT, ALSO TO HO CHI MINH CITY VIA BANGKOK ON THAI AIRWAYS, BUT BOARDING FROM CALCUTTA, INDIA WAS ALLOWED TO PROCEED WITHOUT RETURN TICKET.<br> <br> DESPITE MY BEST EFFORTS, I HAVE NEITHER RECEIVED A PROPER EXPLANATION, NOR A SIMPLE APOLOGY FOR SLIPSHOD SERVICE. OR IS IT A DELIBERATE PLOY OF SOME ROGUE EMPLOYEES ON THE ROLLS OF THAI AIRWAYS ?
