Rudest owner with Bad attitude

Me and 2 close friends of mine went to this restaurant, had lunch and a few drinks (****tails, shooters) - we asked for the menu to see what they have available - when the bill came - the shooters was R3 more than the menu and ****tails was R5 more per ****tail - which adds to a lot of money. When I asked to speak to the manager about this - the owner came - shouted at us and said we don't have to come back. This is so rude and unacceptable. He also said they did not have an updated menu - then I asked why did no one inform us?<br> <br> The Waitress was so good and helpfull - I think there is a chance that this rude owner might fire her.
