Unless a personalisation is done well I don't see a point in doing it. For example why do low cost airlines ask some handling agents here and there (usually in bases) to wear the uniform? When I worked for SEA Handling in Milan Linate (one of Alitalia's mini hubs) it was great as I had a SEA Handling uniform and so when I went to check in another airline I would just stand up without needing to change...
