"No service."
As youngmaf mentioned, no service is precisely what you get in most shops. Staff are too busy talking to their colleagues about their forthcoming holidays to bother with tiresome customers. I visited a well known supermarket chain only yesterday (I won't name it but it begins with 'T' and ends with 'O'). I only had half a dozen items. The checkout girl did not acknowledge my presence at all, preferring instead to rabbit to her colleague on the adjacent till. When she'd finished she looked at me:
"Well how much do you want then?" I asked her.
"Oh, er [looks at till display which I cannot see because it's turned round towards her]..£8.29. I fought you were payin' by card."
"How would you know that? You barely know I'm here at all."
She turned away. I imagine most people in that position would have been embarassed, but I don't think she did embarassment.
She grudgingly handed me my receipt and I left with "I'm terribly sorry to have interrupted your morning by coming here to do my shopping. Next time I'll use the self-service checkout [which I hate because they don't work properly]. Hopefully by then you and your mate next door will have been handed your cards and you can spend all day every day rabbitting to each other."
Shops like that are not long for this world - I'm pleased to say
