The last time it was ramadan I was in Asda with a big trolley full of food at the check out.In front of me was an Indian with one item,I thought it would make sense if he used the fast lane.
A quickie
No idea, I'm afraid.
It's a play on fast and fasting.
OH, right. Actually, that's quite a serviceable pun, it's quite neat because obviously they're not buying much food at the time - but you might need to make it clearer, for idiots like me. 
Yeah, you need to reword it because I didn't get the pun either. Is it for standup? With the right delivery it might work as it is.
The opening is too mannered, you wouldn't say the last time it was Christmas for example. And the punch pun doesn't work because he has an item . Maybe he is in the fast lane with an empty trolley?
Jon could you put your jokes in one thread as they are all quite short.
And poor.
I'd just say
Why do Muslims get served quicker in ASDA at Ramadam.
They use the fast line.
But that is Christmas cracker style. And so ... Racist!
I'm Jewish so that so Antisemitic did Nelson Mandela die for nothing.
I've got some Jew in me somewhere on the distaff side but I do love a king prawn!
How about?
In an attempt to cater for our growing multi cultural society, Tesco have announced that during Ramadam, they will be offering a "fast Lane"
Thats better than mine.
I like that you break the stereotype of the Hindu Indian.
Not many Indian Muslims since the partition...
178 million (according to wikip).
