The Unwanted Guest (and Unreliable Tech) by Katie McPhee, European Metro Marketing Manager at Eventbrite (@BriteLondon) I recently held a networking / talks event for the digital community.While the presenter managed to fill the awkward moments while we tried half a dozen options to get it running, we could not get it to work and the hardy speaker ended up having to ad-lib without slides.As one of our high profile speakers took to the stage I was alerted that someone who'd been begging outside had ran in. He'd locked himself in the toilet where a queue was rapidly forming, and was refusing to leave - saying he was experiencing 'issues'.As it was a community event - no sponsors and free entry - all elements were provided gratis and we decided we'd probably be ok not to have someone on the door after the talks were under way.At another event I organised I had 5 small businesses talk about the tools that had made them successful.Big mistake!Not good!
