On holiday last week with DH and DC.
DH tells me of the following encounter .
DD (3.4) helping herself (he was lifting her up) to the buffet food. She wasn't messing about but is slower than an adult, she was helping herself with a large serving spoon to something or the other.
Woman comes up, removes the server from her hands (no word muttered) helps herself to the food and then puts the serving utensil back down and walks off 
She wasn't British (German I think) but surely with or without language barriers this is utterly unacceptable.
DH says both he and DD were too shocked to say anything.
It wasnt as though there was a large queue, it was a help yourself buffet and no one else around.
Surely she could have waited!!
