I play rugby in england and have seen this done on numerous occasions, even at the 1sts level. Don't feel bad.
Also, there's no way you guys are that slow. Does your coach yell at you for moving the ball out of a ruck too quickly because the entire pack is still on the floor from the previous 2 breakdowns?
Do you play teams that trash talk after the game saying "if you ran the ball at us (forwards) we would've beat you."
My club generally kicks then wish we'd gone for the tap... he really shouldn't feel bad!
