Does it make sense for the crew to refuse economy class passengers to use the first class toilet?

Personally, I think this is also reasonable. Let's think it over. Why do airlines set up first class and economy class? Exactly, because the consumption level of customers is different! Because airlines are also profitable, that is to say, they are also commercial operations. Moreover, Fiona Fang cannot be achieved without rules. The reason why we live in such an orderly society today is that we obey some rules. So I think obeying the rules is also a reflection of our quality. Objectively speaking, if the first-class quality resources are used by economy class passengers at will, it is an unfair treatment for first-class passengers. But as far as the system is concerned, I think we can improve it a little bit like this:

1. You can use the toilet when there is no one in the first class.

In fact, even so, some friends may say, why can the first class be used when there is no one at all? Isn't that unfair? In fact, what I want to say is that there are not many first-class seats, and the comfort of the first-class environment is of course beyond doubt. But if there is no one, the airline can ask our passengers not to fly first class, but the toilet can be used by everyone, just like the ticket is discounted in the off-season.

The toilets in the first class are the same as those in the economy class.

Passengers in first class do spend more money than those in economy class, but I personally think that as long as the comfort of first class is adjusted and the service is provided well, as long as the toilet can meet the most basic needs, it should be possible, because it is possible to go to the toilet as long as it does not delay the first class, and even two toilets can be set up in first class.

3. Set up a high-quality public toilet.

Actually, regarding toilets, I think the requirements of passengers in first class or economy class should not be too great, so in this case, we can combine two toilets into a better toilet for everyone to use together.
