There is a difference between 'racism' and a statement to the effect that many of the staff do not have an adequate grasp of English.
Those Eastern Europeans who work in London generally have very good standards of English - go into any bar or restaurant in Town and that is evident.
Whether they are pink, green or sky-blue pink or from which country they come from is utterly irrelevant; what is relevant is that employment of staff who are unable to communicate satisfactorily is unacceptable.
How on earth you can deem such views as 'racism' is frankly beyond me. Race and communication are totally different things.
