You can go to dinner with he and his clients when it is obvious that you're in a social setting, even if you talked all night about RE (but be careful what you say).

Buy them lunch or dinner and bring a few of your deals to them to review the numbers and make sure your offers were fair.2.  

My tenant has moved in last weekend with my special treat for welcome dinner.

. :) This year after a tough day of financial planning, we treated ourselves to dinner.

As @Jay Papasan said, folks I'd enjoy having over to dinner. 

Mark,I guess it is illegal if someone brings a buyer, and you say to think you, and I will buy you dinner or pay your car payment because I like you.

LOL That's a good one Chris.My clients I meet one on one in person for lunch or dinner or if they are out of state or the country we e-mail, talk on the phone, occasionally Skype, etc.These REIA's just seem like pitch fests in some cases as mentioned to extract money from newbies.

If you're willing to help Account Closed out with questions about his topics in exchange for a dinner, please let him know

So on the next trip out, give me a call and we'll all do dinner.

Let me know if you want to meet for lunch  / dinner sometime.
