I have just checked my makaton video and for burger it showed as I said. True about the dialect shiny, different regions have different 'accents' and it gets even more confusing with different types of sign language. I mainly use makaton wherever I go but my first shift at a place that uses BSL was interesting to say the least and I found that sometimes the same sign means two totally different things between makaton and BSL, they was probably thinking what the hell was I going on about (or what the hell I was on )
Also I have heard about a sign language called pagent gourmet? which is used up north I think and to confuse it even further some people will use their own variations and its a case of knowing what means what to who.
Oh and the drawn signs can be a bit confusing at times wheresthehamster, thats why I like my video as there can be no confusion
