Here's the dilio guys!

  I don't have a problem if you want to work in a bar or restaurant. Is the other way around. I woud like that more and more people could feel what I feel when I work in a restaurant, the fun that I have when I get behind the bar and do my drinks. Yes there are a lot of hours of work, you have to work with people that have no business working there, but trust me is the most fun you'll have in a job ever. Guaranteed.
  My problem is with your boss, supervisor, Head waiter, Head bartenders, Maitre'D, and everybody that is above you in a restaurant. This are the people that are supposed to train you, the people that are supposed to help you understand what you're doing, so, here are a few tips you will need in order to make a good impression on your customers, and yes your bosses too.

1. If you are working at the bar. ( Bar tending )
 Learn where everything is. Go to your shift 10 min early, check where the juices are, check if you have drink garnishes, check if you have silverware for the people eating at the bar, check if you have ice in your ice bin, check if you have napkins in your napkins dispenser as well as straws and drink stirrers  in your dispensers. Check your glassware, make sure that the glassware isn't chipped off make sure that is clean, no dust no lipstick, check that your bar stock is full, that way you won't run out of liqueur on a rush, and never wait for the barbacks to do all this for you, because it won't get done.

2. If you are working the tables (Waiting tables)
 Do pretty much the same, check where everything is, don't be afraid of your customers, but be respectful. Remember these are your customers; they are paying for your job. Never, I said NEVER give a customer another customers check, this looks sketchy. When a customer is asking you about a plate of food know what to say, so learn the menu, know the ingredients, if you have tried a menu item and you didn't like it, don't say it to the customer, this looks really bad, so never badmouth the food that your chef has put out for the customer.

3. Have fun, but be respectful.
 Is important that you have fun in your work, but remember that we are serving customers and some of them are there to have a good time, but they are there to have a good time with themselves not with you. Give your customers space to talk to interact.

4. Always  be on the look out.
 As a server, bartender, you should be aware of the entire restaurant. You should know your regular customers from the people that walk in for the first time. Always be aware of the people intoxicated, try to avoid problems between customers. Count the amount of drinks your customers consume, remember you might be liable for any accidents outside the establishment.

I know that this is a lot to take, but trust me this will help you.
