*Customer approaches an employee while holding a Yoga block.*
Customer: Excuse me, are these the only Yoga mats you have?
Employee: We have Yoga mats down that aisle.
Customer: So these are the only ones you have?
Employee: If you have seen the ones down that aisle then yes those are all we have.
Customer: So...this is the only kind?
*The customer now presents the item she is holding as if to imply it is a Yoga mat.*
Employee: That isn't a Yoga mat. That's a Yoga block.
Customer: So...this is the only kind of mat you have?
Employee: That is not a Yoga mat. It is something else used to support your body during Yoga but it is not a mat.
Customer: Okay...so do you have other Yoga mats??
Employee: ...That is not a Yoga mat. Our Yoga mats are down that aisle I showed you a moment ago.
Customer: Ooooooohhhhh!!
