Not to sound old and crochety but either the social anxiety or entitlement in the next generation is astounding. We have a small metal trash can clearly labeled "Trash" right next to the donation box in front of our registers. Kid pays for meal, gets change and dumps it in the 'Trash'. Cheerily I corrected him and patted the donation box to solidify my point. He just stared at me, and when I actually dumped the coins on the counter and began putting them in the donation box he walked away.
