Un-manned petrol stations are quite common on the continent. Tescos are
pay at pump only at night.

A judiciously placed comma would assist the readability.

On the Continent? I've done many pay-at-pump transactions at Tesco in UK
during the day.

There are two ways to parse the above quote:

1. Tesco offers pay-at-the-pump at night only.

2. At night, Tesco only offers pay-at-the-pump.

I assumed he meant the latter, i.e. that pay-at-the-pump is also
available during the day in addition to some other option(s).

Then there's the confusing association of Continent and Tesco.
