Disagree. If you are allowed to purchase it in Bahrain and enter the aircraft (assuming it's UA981), just keep it hidden if you aren't leaving the airport. The luggage scanners aren't until you are already past immigration, so no one will know you have it if you stay before that point.
Was there a few days ago, the main Dasman lounge was closed for renovation. There is a small satellite lounge at the end of the terminal. Pearl lounge is open, however.
