text_A: The "snug" was a small private room or area which typically had access to the bar and small tinted-glass windows, set at a comfortable head height for those inside. A higher price was paid for beer in the snug and nobody else could come in who hadn't paid the entrance fee. It was not only the wealthy visitors who would use these rooms. The snug was for patrons who preferred not to be seen in the public bar. Ladies would often enjoy a private drink in the snug in a time when it was frowned upon for women to be in a pub. The local police officer might nip in for a quiet pint, the parish priest for his evening whisky, or lovers for a rendezvous.
text_B: If a local police officer, or maybe a tax collector or process server wanted to keep an eye out for certain locals who might come into a bar and if possible remain hidden himself (though with priority given to being able to see others) would he be better off sitting at the public bar than in the snug?
NO.
