[quote their CEO]Our Colleagues
We know how important it is that you receive a satisfactory service from our staff at all times.
So we expect our colleagues to:
be polite and helpful
consider your safety and comfort
wear their appropriate uniform
wear an identification badge
[/quote]
so if there's no identification badge, you could be fairly sure that they are not irish rail staff
like if they are not polite and helpful; obviously not irish rail staff !
