Management

So I recently got a job managing a restaurant.  I will tell you what, from the other side, there is a whole new level of bullshit you never get as a server.  Like every server approaching you during a shift and whining that they want to go home, or explaining to someone why if they eat every morsel of food on their plate then say they didn't like it, I will in fact still make them pay for it. 
People, don't insult me.  I can smell you cheap ass-holes a mile away.  If you walk into my restaurant thinking you're going to get something for free, good luck.  I'm a bullshitter and I will call you out. If you eat everything on your plate then complain about it, I will smile sweetly and say, "okay next time I will absolutely have the kitchen recook your burger if it is done incorrectly". If you complain about something minor, then say, "oh its not a big deal" then act appalled when I don't take it off your bill, get a clue.  I'm not running a charity, I'm running a business.  If you care enough to complain, care enough to follow it through.  If you don't want to pay for something, don't eat it, alert the manager that your meal was unsatisfactory, and expect it to come off the ticket.  This is not rocket science.  If you tell me that you are fine, do you want me to badger you into admitting that you hate your pizza? No. You don't. Be honest, communicate openly, and don't make me hold your hand.
