How, does Liberty Travel ( agency ) stay in business ?

No offense intended if anyone works there, or uses them, but....I never see any clients in their offices.   The one in White Plains always seems devoid of customers.  I see agents sitting at their desks, but nothing else.   Don't get me wrong, I don't go past it every day, or even every week.  But whenever we do it's dead.

We booked a trip with them years ago. A stay at an all inclusive in Antigua.  Terrible experience.   Not only the AI, but dealing with LT.   What a horror show. Obviously we never used them again.  But whenever we see one of their offices, in a mall, whatever, it always looks empty.     Anyone have any info on Liberty ?   Have you used them ?  What was your experience like ?
