Still, I want to know what is happening behind the scene as to those
transactions that are being rejected.

Easy. The pump puts a reserve on your card of anywhere from about $75
to over $200. You pump your fuel and the actual amount is charged. In
a couple of days (while they use your money), the reserve is lifted
and the actual amount charged.

If you buy gas several times a day, you can easily max out a card that
doesn't have a lot of head room.
