our restaurant customers say the darndest dumbest things

and here are some examples of them:

1. Customers, after entering the restaurant through the front door, ask the host(ess), who has been in the air-c0nditioned restaurant since the start of her shift, "What's the weather like on the patio?" Some of our hosts are savvy enough to inform the customer that the weather on the patio is not unlike the weather outside the front of the building, which the customer should be quite well acquainted with, seeing as how they just came from there.
   
   
2. "Is that real ice?" This is a frequently heard query regarding ice sculptures as well as a large glass sink of crushed ice holding martini glasses (which exists in the bar where I currently work)...to which I frequently can't help but reply, "Why wouldn't it be?"
   
   
3. "Do you know where the restroom is at?" OK, I hate the whole preposition at the end of a sentence, but give me a break. Of course I know where the restroom is located - I work there! C'mon, folks, don't be so silly. Ask me where it is, don't ask me if I know where it is! And please don't tack an 'at' on the end of the sentence! KThnx.
   
   
4. When they have finished their dinner and their dessert, I always ask if there is anything else I can get for them, hoping that perhaps they will order a glass of port or a nip of scotch to end their evening. At least once a month, however, someone will reply with, "a winning lottery ticket?" and the entire table will burst into laughter as if that is the funniest thing they've ever heard. I refrain from informing them that I could likely retire if I'd had a dollar for every time I'd heard that one.
   
   
5. Folks call on the phone and will ask "How busy will you be at 7 o'clock?" Gee, I dunno, let me pull out my crystal ball and check! I know, on the weekends especially, it is relatively easy to determine that we WILL be busy, just not HOW BUSY. Sure, we can look and see if there are alot of reservations, but sometimes there are a lot of walk-ins as well and sometimes not. C'mon folks, really, how we would be able to give an accurate response to that?
   
   
6. Cutomers will ask me a question about an item on the menu or whether or not we carry a certain item. After responding (with confidence!), some will look at me and say, "are you sure?" Please. If I wasn't certain, I'd say so - or I'd excuse myself to go and make certain. If you ask a question, please just accept the answer that you are given. If someone asks you a question at your job and you answer them promptly and with confidence, how would you feel if they came back with "are you sure?"
