The big guy behind you

From Ron Hutchcraft:

Roger was assistant manager of a buffet restaurant. He's on our ministry team,
and the other day he was telling me about a special memory from that job early
in his working career. It seems there was a male customer who had been really
abusive to the waitress. So Roger, being the ranking officer in the restaurant
at the time, had the joy of trying to confront this gentleman - well, this man
anyway.
Unfortunately, this abusive customer was young, strong, all muscular
and bulked up. And Roger's like me; he's not exactly Goliath. But he walked into
the lion's jaws and he bravely asked that man to leave. Initially, the customer
was ready for a fight. Then suddenly, unexplainably, he raised the white flag
and he just left, leaving Roger a little baffled as to why this man had suddenly
given up. That's when my friend turned around and saw one of the chefs who had
been - unbeknownst to Roger - standing behind him all that time. The chef was a
Goliath! Roger said, "Suddenly I understood that it was the big guy behind me
that made the difference!"
