Sorry for the late reply.
What is the best advice you could offer to someone trying your pizza for the first time after hearing you make the such a great pie. Is there anything they can do to ensure they don't get a sub-standard pie?
This might sound weird but go into a place with average to low expectations because if you go somewhere that's been hyped up so much you get something you start thinking its going to be so amazing and then even if its really good you still seem to be let down because you though it was going to be some magically pizza. That's my train of thought at least for everything I do. I try and form my own opinions about food because every single person has there own taste. But your last sentence is kind of insulting because you're insinuating that the person opening, dressing, or tending the oven isn't trying to make every pizza perfect. So when someone comes in and says make mine the best of your ability it's like "What do you think I'm doing, trying to send out crap quality product. of course I'm doing my best".
I don't know what you do for a living but say you were a surgeon and your patient said you better do your best work on me, you're going to think "Obviously. What you think I'm going to half ass other peoples surgery and your a specially chase".
Ok, being a pizza chef
I don't make the pizzas, I'm one of the only 2 people aloud to tend the oven during peck hours(5-9). Plus even if I was making the pizzas I wouldn't call myself a "chef" but that's my own pet peeve when it comes to people giving themselves self proclaimed titles. Like line cooks calling themselves chefs is funny to me and insulting to real chefs.
I was at one pizza shop and they allowed the customer to specify the type of crust preferred. I can't recall the details now, but I think "extra crunchy" was one of the options. If I owned a pizza shop, I think I'd consider something similar. When feeding the order to the pizza chef, I'd specify the toppings, soft, regular, or crunchy crust, and NEW CUSTOMER. NEW CUSTOMER would tell my pizza chef to give it some extra care to ensure we get this new customer as a permanent customer.
People order "well done" or "lighter" baked pies all the time and well tell them being coal fired it's already at a "well done" stage and they still want it. But there are draw backs to that; and something we would get blamed for because of something the customer doesn't consider. One if you want it "lightly" baked that's fine, I don't mind doing that at all, but being lightly baked and not letting the dough go through the full stage of baking means there might be some "raw" or gum lines here or there and you will get "bad reviews" but that's what they wanted and even if it was specified before hand. On there other hand getting it well done it can be drier than usual to what the customer might think well done is and again you will get blamed for making something in your words was "sub-standard" even if that was what the specially asked for because the saying goes "The customer is always right...".
These might not be the answers you were looking for but it's how I feel and I don't want to speck for other people who are servers in a food establishment but many feel like customers can just say or do whatever they want because they are the ones "paying you" l and because of that stupid ass "the customer is always right" saying.
And I don't want you to think I'm being hostel towards you I'm just specking my mind in general about how I feel about the questions asked.
