Married women, being already “taken”, make for a safe flirting partner because there’s no risk for anyone involved and no real downside to a little innocent flirting with a stranger she’ll likely never see again.
A married woman is still a woman and married women generally like to feel that they are still attractive to the opposite sex. That means your flirtatiousness will very likely be received in a friendly manner, she’ll be open to a little harmless flirting with you.
So it’s a win-win situation: she gets to feel attractive without breaking her marriage vows, and you get to practice your flirting skills without risk of rejection.
One caution: feelings are real. That means that if you flirt with a married woman that you work with (for example) the flirting can get out of control if it gets into a lot of sexual innuendo and such. You both may end up fantasizing about each other and that could lead to more than just innocent flirting.
A better idea might be to restrict your flirting with married women you encounter on a one-time basis, such as at the grocery store.
In fact, grocery stores really are an ideal setting to flirt with married women in a harmless manner.
Look for the tell-tale wedding ring on the ring finger of her left hand. A diamond ring and/or a wedding band is the obvious give-away of a married women.
She could be picking out some tomatoes, or standing in line next to you waiting to check out. One way to open up the flirting is to pay her an innocent compliment.
For example, you can directly compliment her wedding ring, and follow up with what a “lucky guy” her husband is. This will flatter her, and open the door for a little flirting between the two of you.
