Parents queue up outside the nursery entrance to collect their DCs at home time. Today, once again, this parent parked their big SUV type thing on the double yellows outside nursery entrance and left the engine running (car empty) whilst they queued for 10 minutes to pick up their DC. There is a dedicated nursery car park around the corner with spaces free so it's not like there was nowhere else to park.
I politely suggest that this is not great for air quality in the nursery as the car is next to the open nursery windows for the room where our DC are based inside.
Parent is offended and gives me some spiel about how they have read studies about it being more environmentally friendly to leave the engine running.
I explain that I would rather not be breathing in the emissions while I queue and they reluctantly turn off the engine.
Was I being unreasonable?
