You would testify to the validity of your pics in court that the pumps were labeled..... at the time of your shop.
The shopping company freely admitted this in the past that they often were challenged in court for the shoppers validity of your pics...
Of course by that time hopefully you have NOT erased them and you can prove your shots have not be altered....
Could you look at your gas shots a year from now and positively say YES those are EXACTLY what you took on date.....
And that those shots were not altered? I would not want to be in court with that challenge.
Any shops could do this... ANY.... just that THIS topic went to one company and if you track back far enough you can find the track record....
