I accepted one free sample and entered a conversation with no visible exit

A person at the warehouse store offered me a small cube of cheese on a toothpick.

I accepted it.

The cheese was good. I said, “That’s good,” because it was cheese and I had been handed it by someone waiting for a review.

She asked whether I liked smoked flavors.

I said, “Sometimes.”

This answer opened a second stage.

She explained the wood used for smoking, the size of the package and a discount available if I bought two. I nodded while chewing. My cart was positioned sideways beside the sample table, and three shoppers had formed behind me. Leaving required either reversing through them or moving forward into the cheese display.

I chose to remain still and become more informed about cheese.

The sample host pointed to a second flavor. I said I was only browsing. She said, “That’s what samples are for,” and prepared another cube.

Now I had accepted enough cheese to feel like a customer but not enough to want two large packages.

I tried, “I’ll think about it.”

She replied, “The discount ends today.”

This was useful sales information and terrible exit music.

A shopper behind me reached for a sample, creating a small opening. I thanked the host, said, “I’m going to keep moving,” and pushed the cart forward.

The entire exchange lasted perhaps two minutes. My discomfort came from believing a free cube created an obligation to hear every detail and possibly adopt the product.

It did not. The host was doing a job. I was allowed to taste something, decline politely and leave enough room for the next person.

What is the cleanest sentence after accepting a sample you do not plan to buy? “Thank you, not for me”? “Good, but I don’t need it today”? And does moving the cart out of the traffic lane matter more than providing a complete explanation of your cheese budget?
