No coffees on Coffee and Cream Menu and ufriendly treatment

At OR Tambo airpiort, Coffee and Cream in spite of their nane has no coffees on their menu! When I asked the waiter about the coffees, he showed me the options on a small phone screen, but no prices given. Had to ask him the prices. Mentioned to him that it would be helpful to have the coffees with the prices on the menu, to which he in an abrupt way rep**** he was only working here. Had quite an unfriendly reception and decided to leave.
