Offer to let other people go ahead of you in line, especially if you're approaching the line at the same time. This is double applicable if you're in a store and the other person has fewer items than you.

This is a small gesture of kindness that in most cases will cost you very little time or effort. It shows consideration for other people's time. Especially in the case of being in a store and letting someone with fewer items than you go first, there is no sense in making someone else wait for you who would otherwise be able to get in and out much quicker.

Let people with a few items go first in line.

Slow down a little and let the person in the lane next to you merge.

Hold the door for someone if you go through first.

Offer napkins to the person at the next table who just spilled their drink.

Help someone pick up things they just dropped.

Say "Thankyou so much!" to workers who help you even though it's literally their job.

Wish everyone a nice day, because we all need a nice day.

During the first of the pandemic lockdowns in my country, I was in the supermarket, which was full of people anxiously buying supplies. In a checkout line near me, a person with a large, full trolley was in front of a person with a small, half-filled trolley. I thought to myself that I wished the full-trolley person would let the small-trolley person swap places with them, as that would be the gracious and efficient thing to do, especially in this busy and stressful time ... and to my delight, they did. I watched as, with friendly politeness, the shopper with the packed trolley looked over their shoulder, saw how much less the person behind them was buying, and invited that person to take their place and go ahead of them in the line. The small-trolley person happily accepted.

I say this to illustrate that watching someone demonstrate grace and courtesy, in the midst of a nerve-wracking situation, impacted even me, an onlooker. Five years later, I remember that moment between two strangers, and the hope it gave me that my countryfolk would get through the pandemic with our dignity and kindness intact. Your kindness and courtesy may make a bigger difference that you realise.

Last month, I was walking into a supermarket at the same time as a car was getting into the parking lot. By law, I had preference, but I was in no rush so i let the car go in first.

Inside, the driver recognized me in line and let me in front if her, thanking me for outside because she gets nervous having to stop traffic to get her car inside places since the other drivers havr no patience and start honking her. It was the fastest "what comes around goes around" I've ever experienced.
