Trying my best to have a 'good one'

The other day, as I was leaving a store with some items I had purchased, an employee said to me, “Have a good one!”

“Thank you,” I responded, but I was a little confused. What was this “good one” I was supposed to have?

Was it a good afternoon? A good day? A good week? Perhaps it was a good year or even a good life.

Maybe the employee assumed I was a drinker and was wishing me a good beer. A good bottle of wine could also be what he was wishing for me. But perhaps he made no such assumptions and was merely wishing me a good cup of tea. I had, after all, just bought some tea for myself. But I had also bought some soap. Perhaps he was wishing me a good bath.

Whatever he was wishing me, why was he wishing me only one? Why couldn’t he have been a little generous and said, “Have a good several!” or “Have a good many!” Wouldn’t I want to have many of something that was good?
