my local post office took photos of my 2 girls at 2 weeks old and as other posts they kept trying until they had a good enough photo, got passports no bother
Mine took some really shocking ones but said they'd only re-do them if I paid for another set. 'We do loads of these, they'll be fine'. Duly rejected by passport office. Went back to PO, showed them the letter and the original photos, they did another set worse than the first then tried to argue that those'd be fine too*. Useless feckers. Took them ourselves against a white sheet, absolutely fine.
*probably went on strike straight afterwards. Taking two sets of photos of one child? surely grounds for industrial action…
