So says the connection page of a a well known national coffee chain. So with a pseudonym, DOB, and an invented postcode I managed to connect without blurting my personal details.
It's all bollo actually. The coffee shop next door allows you to connect without this hassle but theirs was down, leaving me no alternative but to use this network. McDo also asked for my personal info citing the same reason when I tried a walk-by wurdling there, and ASDA go a step further by wanting your mobile number.
If this is a straw in the wind I'll need to create a few more alternate personas.
