Parking at Tesco, Copdock

Evening everyone. I’m currently parked up at the Tesco at Copdock interchange A14/A12. I’ve parked here many a time over the years. Does anyone on here know why Tesco don’t charge a fee?
Was it once a truckstop and when Tesco’s was built they perhaps had to provide free parking??

Just a guess, hope someone can enlighten me.
As an aside, looking at the usual litter and bottles of pi$$ that have been left strewn all around, I’m surprised that they don’t charge something.

Thoughts …

If its as bad as you say with the bottles and the rubbish then unfortunately it probably wont be long till a parking fee does arrive.
