I think hospitality feels busy because you have to book in advance, could get turned away, etc. But in reality, they will be dealing with less customers than they could.
My local pub can have ten groups sitting outside, they could have that again inside, and probably double capacity if social distancing was not in place (especially if you count people drinking at the bar). There's no way they need the same number of staff right now that they normally would.
Because we are a tourist area, this is the start of their "season" so it's likely they won't take their usual seasonal staff on, but those staff will have a shorter period of seasonal work than they normally would- which means less money in the local economy, etc etc.
There are also some industries, like travel outside the UK, events etc, which have been decimated in the last year, and I don't think it will be as simple as them reopening on day one, and getting back to normal for staff.
Obviously it won't be most people- if most people were redundant, we'd be fucked. But job insecurity can be bad for everyone, and it may have delayed knock on impacts on other industries.
