1. Good morning sir/ma'am/ladies/gentlemen/folks (informal)/guys (teenagers; informal). Please have a seat and take a look at the menu. 2. Please go to the cashier's desk, tell them your table number and get a ticket, and a waiter will bring your order to you shortly. 3. I'm sorry, sir, we don't have any tables available at the moment. If you would like to sit down, the wait will be about 15 minutes. 4. If you would just like a drink, you can sit at the counter. (or bar?) 5. I'm sorry, sir, could you please wait in line at the cashier's desk to get a ticket. - Americans don't use "madam"; we use "ma'am". (sounds like 'mam'). - "Folks" refers to older people, both men and women. It is friendly and informal. If you in a formal place, you may want to use "ladies and gentlemen". Polite phrasing: Would you please do this... (polite request; willingness) Could you please do this... (polite request; ability) Would you like to sit, etc... (polite question instead of "do you want to") Would you like some coffee, etc... (polite question instead of "do you want some") Please follow me/please go that way... Always say "please" and "thank you" and "you're welcome" as appropriate.

Hi 1. Good morning sir/Gentlemen/madam/ladies. Please have a seat and take a look at the menu. 2. You must go to the cash desk, say your table number, and you will receive a ticket. A waiter will be with you as soon as possible 3. I'm sorry sir/madam, we don't have any tables at the moment. It is about a 15 minute wait. If you would care to take a seat we will prepare a table for you as soon as possible. 4. If you would just like to have a drink, you are more than welcome to stay at the bar. 5. I'm sorry Sir/Madam, I am afraid that you must wait in line for the ticket at the cash desk. 3 - recommend you offer them a wine/drinks menu, if you can 4+5 - putting your arm out, at waist height to block their path to the tables, whilst at the same time, putting your other arm out at shoulder height, arm straight and palm towards them to indicate the best direction for the bar and looking at their eyes, turn your whole body and your head towards the bar.. without touching them you can guide them in a direction as if you were a mother herding children that you weren't allowed to touch :)

Madam and Sir are good if your'e addressing one person, but don't use Madams/Sirs for groups of people, it's better to say Gentlemen/Ladies. Also, I would use Miss for a young girl. You may also want to change the second sentence to something like "Please go to the cash desk and give them your table number. You will then receive a ticket, and as soon as your order is ready, the waiter will bring it to you". Generally, in English, it's not very polite to tell customers that they "have" to do something. It's more polite to say "please do this or that" or "I'm sorry sir, we don't have any tables at the moment, if you'd like to sit down, the wait is about 15 minutes". Of course, all depends on the intonation, etc. Hope this is helpful. Good luck!
