How do you keep your toddler from running away in the shops?

[Taurean]

I flat out refuse to use a harness, just will not do it. I really dislike watching parents use them, the kids are being pulled and yanked in different directions, IMO boundaries arent really being set (well from what I can tell from friends who use them). (please don't take offence anyone)
We have rules when we go out and both girls know what happens if they break those rules. We turn around, we get back in the car, and will go home. If we get back to the car and they are behaving then we will continue shopping. They know they either hold my hand, Dh's hand or each others hand. If they feel the need to do a runner, then its trolley or stroller (although we dont take that very often anymore). Before giving up, I will bargain with them, normally its a cheesy roll to share, or something similar. But if the tantrum then continues in the trolley then straight to the car. I can always do my shopping another time if need be.

Bargaining with a toddler ain't gonna work, not in my house at least. And getting in the car and heading home if the toddler didn't stay put?? When on earth would a mother get the shopping done not to mention the time she'd waste going back and fourth to the car or to and from the shops!

I agree with the other posters, I just don't get the problem with a harness when we happily strap our kids into prams, trolleys, high chairs and car seats daily. It just doesn't make sense to me that they are so offensive to other parents. I understand non-parents not 'getting' them and how good they are but not other parents. They just aren't that different to all our other 'strap-in' devices we use as parents.
