Had something very similar happen during boarding in Ravenna last month. Fortunately the staff firmly told the offender(s) to step aside and wait their turn.
Probably because the bartender realized what they were doing. Your "friend's" package should have been cut off and and both of them should have been made to pay for their drinks.
Nope, contact Royal and tell them your TA is unresponsive. They can take the booking away from the TA. We've had to do this twice and that's one reason we don't use a TA anymore
