Lies are unacceptable

I simply hate it when someone can casually lie to cover their behinds. The waitress never I formed us about the drinks we ordered. That a glass is R34 and a 1L is R100. When I questioned the bill, she returns saying that the manager advised that I could pay for 2 glasses and that the manager would come to us now. The manager then advises that she never told the waitron that. Why lie? If she misunderstood our order, all she had to do was apologise but to lie is unacceptable. Lying is not a way out. I'm sure "lies" are against your policy. I honestly wouldn't return to your restaurant in a hurry!
