What is a good/affordable gift for a coworker?

a quilted hot mug coaster that is stuffed with herbs... maybe lavender..or cinnamom

I usually get a small potted houseplant. Unless you know a specific snack/treat they like. That always works.

.... pay for their lunch??

that's a tricky one when you think about etiquette.

or extra office supplies.

or a carpool them to work.

or give them a tapped to the max fare card.

for general purposes of functional gifting... things that are useful that can save them the time, effort and money.

for the time being.

What's the gift for M/F?

Get them one of those calendars that has the pictures of something you know they like. Like dogs or cats or horses or scantily clad women. Most everyone would like a nice candle. Yankee candles are quite nice. A gift card for something like Starbucks or Whataburger or somewhere you know they like.

A memory stick. $10-20

A stapler.

50$ lcbo coupon.

A four prong massager .. Its like 1$ at the dollar tree 😁

Flowers

Get him or her some postage stamps with his/her photo on them.

Hm. Eggs maybe. Perhaps some bed slippers

Depends on why type of coworker. I give bath products. To the female ones
