I have had the following conversation several times with one particular employee at my local Tim Hortons:
Me: I'll have a toasted chicken club sandwich combo please, on whole wheat bread, with Coke to drink and a chocolate dipped donut.
Her: A chicken club sandwich?
Me: Yes, please. Toasted, on whole wheat bread. As a combo, with Coke and a chocolate-dip.
Her: What kind of bread would you like that on?
Me: Whole wheat please. Toasted. As a combo, with Coke and a chocolate-dip.
Her: Would you like that toasted?
Me: Yes, please. As a combo, with Coke and a chocolate-dipped donut.
Her: OK, would you like that as a combo? You can get a drink and a donut with the combo.
Me: Yes, please. I'll have Coke and a chocolate-dipped donut.
Her: OK. Coffee to drink with your combo?
Me: No, thanks. I'll have a Coke. And. A. Chocolate. Dipped. Donut.
Her: OK. Coke. And what kind of donut?
Me: Hmmmm... I can't make up my mind. What do you suggest?
Her: I like the Maple dip.
Me: Fine. Maple dip it is.
Her: OK, anything else?
Me: No thanks. There are only so many hours in a day.
Her: Confused look
I suppose that it would help if I said what I wanted up front rather than wasting her time like that, trying to squeeze the information out of me.
