You totally can! Word of advice: don’t make a habit of it. People start expecting it. But our store had someone who recently had a house fire and they lost most of their kitchen. We all gave our coffee markouts

You can “share your markout with your family and friends or donate it to a charitable organization if you don't intend to use it,” so you can probably offer it to them but not offer to use it to pay for something they were planning to buy? The hub doesn’t say you can’t, but it’s probably discouraged.

You're not supposed to trade it for currency, goods, or services because its considered theft, but tbh just don't be showy about it. It's your markout!

My SM gave her markout to a customer who was having a hard time dealing with her husband’s illness
