I see what you mean, nobody expects 100% certainty, but if you’re going to be a Tier 1 shop, you should be able to count on good service and solid standards. That’s what sets them apart.
Even mature shops can have periods where things aren’t running perfectly, but if there’s a lot of inconsistency or new staff constantly learning the ropes, it starts to feel more like a Tier 2 shop, reliable, just not top tier. Great shops should be focusing on being consistent and professional, the way more mature markets do.
If a venue isn’t quite there yet, it’s fairer for everyone to call it Tier 2, so people know what to expect.
