At least 10 years ago, during a Christmas sale at Webster Records, a clerk asked if I wanted any of the CDs I was buying gift wrapped. I declined politely, even though I planned to give at least one of them as gifts.
I probably should have accepted her offer. I've known from an early age that almost everyone wraps presents more symmetrically than I do. In fact, I suspect that my frustration over not being geometrically inclined with gift wrapping caused me to startle some sheep once.
Although I don't think any store should require its workers to wrap customers' gifts, I always appreciate the courtesy of the offer.
