I think there’s a large emotional aspect: If you’re hungry and a bit tired (from a lot of exercise not stress), generally in a positive mood, and not super focused on the taste of the food then it’s going to taste a lot better than if you don’t particularly feel the need to eat, you’re a bit stressed, and you’re focused on perfecting sausage flavour.
In other words, it’s probably quite easy to enjoy an ok sausage if it’s come from some random grill in a park because you’ll be focused on having a good time with your friends or family in a park more than on whether the sausage tastes good. If you make it at home (even if you’re inviting those same people) you can easily get yourself worked up about cooking the perfect sausage and whether the temperature is right and whether the time is right and so on, that you’ll just feel like the sausage doesn’t taste so good (and you’ll probably be more careful and critical about tasting the sausage).
Then again maybe the sausages were just undercooked in the park. Or maybe you used different sausages (I’ve found much more variance between sausages being made differently than how they are cooke)
