That is one of those anecdotes that doesn't work, that isn't how the world of shower heads is, if your hotel is using one that isn't very good, then tell them they need to get one that works.
Israel almost certainly uses water saving shower heads also but the quality of the shower heads vary from model to model, if you live in a modern home, then you probably have a water saving shower head.
It is about shower heads that work well, not low flow versus old models from the past, just like toilets.
Actually, it’s about shower head design AND water pressure.
I work with spray jet patterns and such, so the subject is one I’m familiar with.
If every hotel that I’ve stayed in in America in the past two decades has water saver shower heads, either required by law, or to save money on their water bill, and had lousy water flow, and every shower on an eight day tour of Israel had more than adequate water flow, I think my anecdotes work.
Even our Israeli tour guide was perplexed at the water flow in our hotels’ showers.
If a shower head restricts the water flow as a misguided water saving measure, or a more rational attempt to save money, there will be less water coming out of the shower.
