Dear Car Owner,
I have worked here three years. We do not sell winter tires. In my time here we have never sold them. Sure I'll check in the back, but I'm 100% certain you didn't buy some here last year. No, I'm not trying to imply you don't know what you're talking about, but we're a pharmacy. We don't even sell milk. I'm just saying.
Sincerely,
The Tech
