Cash Register Talk Regarding Conditioner Without Shampoo

I had a laughable moment at the cash register the other day.  I went to Jewel to grab a few groceries and remembered that I had a half a bottle of conditioner left.  I grabbed two bottles of Suave Naturals Tropical Coconut Conditioner and a few groceries and proceeded to the check out counter.  The cashier stopped after ringing one bottle and said, "You know that you have 2 bottles of conditioner right".  I laughed and explained that I use conditioner as a leave-in and that I didn't intend to purchase shampoo.  For some reason I didn't feel the need to explain that I also frequently co-wash my hair with conditioner as well.  I think the conversation would have resulted in a blank stare and additional questions, and I didn't want to hold up the line.  I graciously told her thank you, because she did check to make sure that I didn't forget the shampoo.

I wish the cashier would have told me that a few months ago, when I mistakenly purchased a shampoo and conditioner.  I almost mistakenly co-washed with a shampoo and then almost put it back in my hair as a leave-in conditioner on another occasion.  Both bottles look exactly alike.  Whew!  I don't need that kind of error.  LOL! 

Have you ever been asked if you forgot your shampoo (especially for those co-washers out there)?  Do tell about the conversations at the cash register.
