Aidez moi je sais pas comment faire c'est pour demain... You had a message on your mobile phone telling you that someone called X was expecting you in a café Im

Hi, where are you?  I have been here for half an hour. I have already had a coffee and a muffin.  I cannot wait much longer.  I thought we said 4 o'clock.  Please call me back soon, because I will leave in a quarter of an hour. I am ordering another coffee and will leave when I am finished. See you soon or call me back.
