Well anaidross, you have a real problem here. She is a female and your mother.
To her defence I have to say I understand her attitude very well. Age 44 I realised that I cannot handle the challenges of air travel on my own anymore. I had the same fears like she has now. But I am not your mother.
When I remember correctly I saw at BKK a small lounge for pax not speaking English or Thai and all other kinds of special requirements. Never paid much attention to it. To my defence I have to say that riding the wheel chair with the boys at BKK is always fun. Most WCHR pax are very grumpy and the boys have not a good time working, but we allways chat, joke and laugh at lot. So my attention is always distracted.
Maybe some other user can be more helpful. Sorry.
