I used to work for a company that held speed dating events all around the country and occasionally one person wouldn't turn up so one person would be on their own for 3 mins. So I would try and go round and talk to them so there weren't on there own for that time.
Obviously it is slightly different because they knew I was working for the company therefore it took away some of the 'pressure', but it was amazing how quickly the 3 minutes go when you are just chatting away!
Some 'dates' are bound to be easier than others as some women will be chattier than others! I don't really think you can plan what to say as each date and lady will be different!
Just try and be smily, chatty and interested in what a woman is saying and you should be fine.
It's only 2/3 mins and it will go quickly! When i blew the wistle after 3 mins for the next date to start lots of people would look at me as if to say 'was that really only 3 mins?!' or they would actually say 'the time is going too fast!'
Don't worry you will just fine and the staff from the company should be nice and friendly to you - flirt with them to build your confidence up when you first get there - they will be used to it trust me ;)
Anythin else you want to know about it just ask me :)
Happy dating - good luck
