When I was working minimum wage at a gas station many eons ago, we would have '2 for $x' specials where x is less than 2 times the individual price of whatever item.
People would often not want to buy 2, but I would ring up 2 in the till for the special price and charge them for the single. Then when the next person did the same, I would charge them for the other single.
So over the day, I would sell 10 energy drinks at say $4, but ring them up as 5 '2 for $6' specials. This would put the till up by $10, and then I would use that $10 to have a free meal.
No, but I had a small company and asked the worker bees to define their own perks.
There were four employees. Three of them played paintball together and wanted paintballs. So I brought a case of their favorite balls into the office before their outings. The fourth guy wanted to have baby carrots to snack on. He ate ~3 lbs a week. Dude would code for hours as long as he was crunching carrots.
I couldn't have guessed what any of them wanted but they were absolutely cranked by getting it. This was a huge lesson for me: ask people what they want.
