I have expressed similar views to these before and have been called racially prejudiced.
However I am sure that I am not the only person who finds the apparently never ending increase of poor social ability and atrocious English speaking staff in more and more shops and stores as completely unacceptable.
As Max Bygraves used to say "Let me tell you a story"...
Earlier this week when I tried to buy some Cranberry juice at my local Somerfield's convenience store and found they were out of stock, I was told by one of the only white British staff that they were expecting a delivery of cartons of Cranberry juice that day and I should call back in a day or so.

And today was that day.

The shelves were fully stocked but there was still no Cranberry juice on display. So, just in case it may have been moved elsewhere I asked a staff member, who was right by the shelf, if they had any Cranberry juice in stock yet.
He looked at me and said "Wha'?".
I repeated my question and with a frown crossing his brow, I received the deeply afro-carribean accented reply "Orange juice there" accompanied by a nod of the head toward the shelf.
I said that I didn't want orange juice, I wanted cranberry juice. The man frowned again and repeated my words in a question-like manner to which I replied "Yes, cranberry juice".
He just stared at me vacantly and would probably be standing there still if another member of staff had not approached. He joined in and in barely understandable accented English enquired if I wanted "you won cranbry jus" (Honestly it was that bad).
I replied yes I did and that I had been told that it was due in by now. Could he please tell me if they had any as it didn't seem to be on the shelves.
He then ran his finger along every carton, his lips mouthing the words printed on each but plainly conveying nothing to him whatsoever other than letting him reach the conclusion "No."
The arrival of assistant three, possibly a manager as he wore a shirt and tie, fared me no better as his response , in an extreme southern Asian accented English was "No Sir we don't stock cranberry juice. We never have. we don't do it."
Now I get the right hump when I'm bullsh*tted by staff who just can't be bothered to do their job.
I directed him to read the large shelf label beneath the cartons that clearly proclaimed, in large letters "3 for £3" and listed all the various types including, of course Cranberry juice.
I then pointed out to him that I had been buying an average of 3 cartons a week from this very store for several months and that they did indeed always stock it.
I now had three members of divers ethnic backgrounds staring at me in confusion as if I was the one speaking a language foreign to the soil we were on.
As no one of them was showing any signs of coming up with a useful comment I asked again if they were going to be getting any stock in this week.
Assistant 1 and 2 immediately walked away leaving assistant (manager?) 3 staring at me but still not answering.
I shrugged and went "Well?" and received the reply "orange juice, we have that"
I gave assistant 3 my other goods as I really couldn't be a*sed to give them any money for anything.
There's an old adage "Pay peanuts - get monkeys".
I'd suggest that Somerfields should consider employing monkeys, they may at least have a better grasp of English and basic social interaction with customers.
