Ideas
I can confirm that I noticed the same thing in two different saves. I didn't notice it in a third, new save but I realize now the difference was I didn't have a club gathering going in the new save. I did have a club gathering going in the other two saves. The ability to swipe was available for everyone in the club gathering, this included children and up. In one save I did have a teen with the kleptomaniac trait but the rest of the household/club members did not have that trait. In the second save none of the three household/club members had that trait. This was after the Sept 18 update and I was testing with no mods/cc (never had them in any of these three saves) and playing on Windows 10 DX 11. I have all the packs and kits released to date.
Best regards,

Note I just went into a third save and took my household to a community lot (park lot) and when in a club gathering they too have the option to attempt to swipe, though the icon is different now then it was previously. It also says it's due to the 'sticky fingers' aspiration and none of my sims are on that aspiration. Though this sim has level 3 of mischief skill.
One other sim has the different icon and the pop up saying 'from the Sticky Fingers Aspiration' and I'm guessing I've put them on that aspiration at some point (this is from my event save family so I probably looked at it just to see the details). Everyone else in the household/club (five other sims, including two children) has the usual icon for attempt to swipe, and there is a mix of no mischief skill up to level 5 of mischief skill. No one in this household is a kleptomaniac.
Best regards,
