Sound terrible? When and where would this possibly happen? The answer is that many dogs go through this every day.
In dog body language, showing teeth and a hard/firm stare is considered to be threatening. That threat can be meant to deter, dissuade, or announce action, but there is no mistaking the display. Now let's think about how most strangers approach your dog on the street. They see your dog, and their eyes widen. They can't help but smile, their grin getting increasingly large as they approach. They love dogs of course, but let's think of it from the dog's point of view. Staring, showing teeth, approaching with intent. It can be very difficult for dogs, especially fearful ones, to understand the nuances of human body language that would indicate that this overly enthusiastic stranger means no harm.
How can you help your dog? You can help by coaching strangers, training with your dog, and by understand that it's perfectly acceptable that people do not need to pet your dog.
"Dogs love me!", often exclaimed with ear-piercing enthusiasm and a forward motion of contact. People who love dogs are good people - some just may need coaching on how to say hi in a dog-friendly manner. I am fortunate that my dogs are well-socialized, but I will still offer guidance to people when they want to pet. In my experience, it is best if you tell people 1) the action they need to take, and 2) how to execute it. "She feels most comfortable when you kneel down and offer her your side, so she can choose to greet you." Or, "he's in training, and we would love it if you would help - if you could drop a treat as you pass by without touching, that would be wonderful". The general public enjoys dogs and wants to be helpful. Giving them canine communication tips while gaining their buy-in via helpfulness can bring a positive tone while avoiding interactions you don't want. Working with your dog to counter-condition natural human excitement can give your dog a whole new level of confidence in strange situations. Working from afar at first, you can click and reward your dog for calm observance of strangers that smile, make loud noises, run, etc. Think of the typical behaviors that would indicate someone wants to approach your dog, and build on them in training. If your dog begins to associate smiles and squeals with hugely positive rewards, they will begin to look forward to a stranger that demonstrates these actions. You can also teach a "say hi" cue, to give your dog confidence and a sense of choice. I teach my dogs a hand touch in front of knees with the cue "say hi", giving them a consistent action and location to expect handling from a stranger. Giving your dog the ability to choose to interact, with an expected outcome can go a long way. Additionally, "say hi" pays well every time, and my dogs linger and linger with strangers, hoping for extra rewards.

And in reality, strangers do not have to pet your dog. If you can tell your dog is uncomfortable, you are not obligated to proceed. It's more important that your dog is set up for success and builds confidence around people they don't know, than to force an interaction. Always work at your dog's pace, and engineer a positive environment for them. And praise and reward when they choose to approach strangers!
