This reminds me of this incident from last year from Noida. In the morning I had gone to drop my sister-in-law to her office nearby in the morning. My brother informed me that the pressure was low and I should possibly get the tyre pressure sorted as soon as I can in the morning. So I stopped nearby at the first place I could find. It was a road side stop.
This guy first mentioned that the pressure seems to not increase as he is trying to fill it. He proceeded to point out the valve as faulty. Given I was in a hurry and the risk of running on low pressure, opted-in for a quick replacement instead of discussing further. My intuition said otherwise but I still went for it
When I returned home, my brother asked about it and told me about this common scam across roadside tyre shops. Felt stupid and embarrassed that all this interest in cars, and I didn’t spot this!
Avoid roadside shops as much as you can.
Always look closely while you are at the tyre shop.
Keep a valve tightener with you at all times.
A spare valve or two stored in a sealed pack might be better than having to go for a random sub-par option in case of an emergency.
Buy a tyre inflator.
Buy a puncture repair kit.
