> If you can't have a fun conversation over coffee or dinner you probably arent compatible

I don't agree with this. Most people aren't comfortable opening up right away on their first interaction with someone they don't know very well. A lot of people also suffer from anxiety issues which can make it difficult for them to open up right away. Coffee/Drinks help to alleviate that somewhat as they're stimulants/social lubricants. Dinner? not so much, it just makes you full and sleepy.
