I have been through similar experiences, dozens of times at numerous airports, and have never felt the need to get rat-arsed. The problem is caused by a sub-set of humanity who have no regard for others and lack the morals for self control. The only solution is to ensure they are kept separate from booze in the run up to departure and heavy penalties plus a long no-fly ban for anyone who cannot behave. A few examples with their passports stamped "not valid for air travel" would concentrate minds.
