Would like to have at hand some phrases you can use in case you want to end up a conversation? 

Have a look! I found them at learnex.in and hubspot.com

Actually, I have some people waiting for me

I am in a meeting right now, can I speak to you later?

Excuse me, but suddenly I don´t feel too well...

I am sorry but I have a prior commitment

I am afraid it won´t be possible. I have some place to be...

Sorry, but I have a meeting to attend

It´s been great catching up with you. Let´s exchange cards?
