I made the mistake of stipulating that the Steel 5ltr I left for filling was "emergancy" bailout and they very helpfully pumped it to 275bar...
(but then they do have a habit of using their O2 booster to its rated max pressure as well!!!!!!)
I once left an Ali Suitox bottle for filling at a famous UK inland dive site, it came back at 250bar and hot enough to cook bacon on!
Ekkk
