Doesn't the business have a right to keep track of its clientèle? Obvious legalities of underage-ness of a pub aside, I already can hire counters that watch the security feed and assess numbers.
And also, CCTV isn't open to the public or traded around wanton. Instead, I would argue, this data is highly confidential to the business and therefore would guard it selfishly.
And as for the pub photographing: There has been a trend in bars in Indianapolis to scan he barcode on the back of the drivers license to "verify identity". What they're really doing is building up a clientèle database for which they can do whatever with. And they are booming bars.
