Seen boatloads of students, other halves, randoms, OAPs, etc. at both BETT & Infosec. You'll have no problem at all. If you do, ring our office and ask them to get me on my mobile... i'll come out and do my "irritated exhibitor routine" at the ticket desk (sometimes works!!) :)
One of my collegues signed another up as a "Technical Donut Assesser", he wasn't too keen to wear the badge though.
A slight thread hijack, but I should be going this year :D I shall start planing operation "complain loudly at apple stand", "glare at Capita stand", "Roll eyes at microsoft stand".
Should anyone use the phrases "going forward" or "synergy" within ear shot then they will be assaulted with a dictionary or thesaurus.
So you're the guy that runs up to Apple stands, yells "IT'S CRASHED!" and ducks into the crowd!
MS will need asking when the SP3 login bug is going to be fixed.
Not that I think it's going to change anything, but 10 minutes throwing things at the apple stand will make me feel a whole lot better :p
A quick search on google for buzzword Bingo cards brings up some fun ones. I have some adapted for education and have been known to take them to seminars (including those at BETT).
We could all go to a particular seminar with them and a t-shirt to the person who actually stands up and shouts "House"!!!
