If I were a Panera, Starbucks, Dunkin Donuts, etc I would love the fact that people were coming in and conducting business because it would mean business for me. Whenever I meet a client at one of these type places the consultation is usually 30-40 minutes and I usually ending up buying coffee for everyone. Win win
I agree with you on the above. Most rules that DJs have are self inflicted. If everyone had the thinking that other peoples businesses are not their office, then Conference rooms, meetings rooms etc will all go out of business.
Meeting at a mutual place like a Highbucks etc can put both parties on the same level field. It is easier to take subtle control of the situation at these places.
