This might be common practice outside EU and UAE. As far as I traveled, things are still normal and room service feels like an experience - at least it still does in top tier hotels. Probably below 4 stars, where people who spend less appear, you might see some budgeting in matters of room service and not only. As for the hotel not letting every delivery go to the room, I find that smart and safer for me as a tourist. In the end, I will always say that if people don't value their money, time and bodies nobody else will do it for them.
