My missus laughs at me saying tow rai or whatever. She says falangs always rise the tone with question and 'talai' with a rising 'ai' sounds "falang mak mak".

I've since learned to say it posh Thai style with the rolling drrror drrrreua and correct tone, but she laughs even more and it always gets a smile from the Thais, anything with the Thai "r" pronounced correctly.
