Student: He’s a little older than I work with but I definitely know a few like him 😂
Her: 😂 When should our date be?
Her: Hahaha yeah he really is something, he once told a woman she stank in the shop and I immediately had to remove him. I was mortified 

When are you typically free?
 This works well as he is asking her when she is free instead of suggesting days on which they can meet up. This reduces the risk of her flaking on the date.
