re: How long is too long?

If you go in and after a minute they haven't seen you, take out your phone act like you are answering it. Say "Hello" "Hey I am at __________ about to get something to eat whats up?" pause for about 15 seconds then say "Look, we can talk about it when we get back.........." Don't yell and make it obvious, just talk loud enough that they hear you. If they still don't come.. Leave
