Should school dinner ladies make unhelpful comments?

I AM A DINNER LADY TOO, AND I NEVER HAVE DARE TALK TO CHILDREN LIKE THAT, MY DAUGHTER HAVE EXPERIENCED SOMETHING AT SCHOOL...THE DINNER LADY TOLD HER THAT THERE WAS NO MORE HAM SANDWICH SO SHE HAD TO EAT CHEESE SAND WHICH SHE HATES CHHESE, BUT THEN SHE DISCOVERED THAT ANOTHER GIRL WHO WENT FOR LUNCH AFTER HER GOT HAM SANDWICHE, I THEN LATER FOUND OUT THAT THAT GIRL WAS ONE OF HER FAVORATE, I THEN WENT TO HEADTEACHER TO REPORT HER, SHE GOT A WARNING AND MY DAUGHTER NOW IS MORE HAPPIER WITH PACKED LUNCH.
