Haggling in UK

I once had my 1st cousin visit in the UK and that’s when it really hit me how much I’ve integrated into living here. It was a funny experience when you see a newcomer and you see yourself from a few years ago struggling with fitting in a new environment but my cousin was something else. We went into a sport shop and he was looking at getting some trainers:

Cousin: Hey Tobasco these look nice. I think I am going to get them.
Me: Nodding *anything to finish shopping quick*
Cousin (to shop attendant): How much this? (in broken English with Arabic accent)
Shop attendant: Its 65 quid
Cousin: What 65 quid? What you mean?
Shop attendant: 65 pounds
Cousin: Okaay. How much last?
I start to smile because I think I know whats coming and I am going to stay quite and enjoy myself.
Shop attendant: *gives weird look* huh?
Cousin: Last how much? You know?
Shop attendant: You mean price.
Cousin: Yes, how much you give me last I take
Shop attendant: I am sorry I can’t its fixed prices here
Cousin: No I give you 40 for this
Shop attendant: *getting frustrated now* No you don’t understand its fixed prices here I can’t.
Cousin: What fixed no fixed khalas I give you 45 for this no more or I go.
Shop attendant: *looking in disbelief with mouth wide open probably thinking WTF I don’t get paid enough for this*

Then I couldn’t hold it anymore and I put the poor shop attendant out of her misery, explaining to my cousin that you can’t haggle in UK shops like we do back in the UAE. He was embarrassed a bit but then starting laughing. It probably hit home what the shop attendant was trying to say to him all along.

Good times.
