Rarely are we inclined to go into restaurants of coffee houses that have no visible business with folks sitting outside or cars and bikes crammed into the parking lot...go to shops that show signs of life as it surely indicates better coffee and probably friendly folks inside...which leads to the next sign that baristas and employees should be able to say "Good morning" or "Can I help you?"...if you are avoided like a plague then the shop probably isn't interested in your business...another obvious sign is if the employees are ragged and unclean looking as well as the workstation around the espresso machine (an unavoidable fact in a super busy coffee house)...lastly is if the barista does not know the type of coffee being served (not light or dark roast) but the actual beans from Sumatra or Central America (Guatemalan) then it shows disinterest.
Good luck out there.
