Useless Air hostess

I requested a glass of wine and glass of sparkling water - air hostess - says only one drink - I say but on the way down to Cape Town I got two drinks - she says no because it’s a full flight - I say but the two people to my right are both sleeping etc - zero common sense - not friendly - wrong industry - should rather work in a mortuary - (unfortunately I didn’t get a name but I have a photo of anyone from Lift is interested in the staff member I am referring to) (CT - JHB 4pm flight 14/10)
