Manager doesnt know how to treat customers

We went to spur for a mothersday dinner after 10 minutes the electricity went off after our order the waiters couldnt explain what the problem was so after another hour the manager came to tell us he phoned the owner the owner said that the electrcian is out of town so they dint know what to do we then said the whole evening is messed up because we cant just sit and wait for food so i told the waiter we are going to leave , they gave us the slip and then the speed point didnt want to work so they said sorry i have to go and draw money at another banks atm where they charge me extra bank costs but they dont mind just aslong they get their money for bad service and the waiters standing and laughing at you if their speedpoint isint working that is really disgusting
