Some people definitely do and I've encountered many of them in high end dining (as an example). However, the experiences I've had with staff at these properties are totally unlike that. Probably the closest comparison I can make are the well-known rules for Disney employees. Every employee on Disney property is essentially in costume and portraying a character, whether they're in a physical costume or not - to the point where every employee is referred to as a "cast member". These brands have their systems, procedure, and process down to the point where virtually no personality or individualism is expressed by individual staff. Excellent for service and experience, but as referenced in my original comment, it can kind of cross over into "uncanny valley" territory and get unsettling.
