Husband and wife buy two "Two dine in for £10" meal deals,

with whole chicken and Salmon Gratin.

They ask for two free bags (which are supposed to be be for sandwiches etc...) and I said that I couldn't do that for what they had bought.

They both huff and puff about how I should give them a free bag as they are shareholders. The husband says:

"Boots give away free bags"
and I reply: "Yeah, but they don't sell Salmon Gratin, do they?"

Rather pleased with myself, I smile at them (thinking I had a well deserved victory).
The wife then says: "Yes, but Boots sell LOTS of things you don't".

Dear me... I feel she missed the point.

I'm wasted there.
