Gloryholes and Adult Bookstores and movie theatre.

A lot straight guys go to adult theatre and are not interested in
sex with men.

These guys usually sit in a different " non-cruisy " area of the theatre. Crusing around the theatre is fine but realize some guys just want to be left alone and being overly aggressive can be dangerous and results in complaints to the management.

Most straight guys looking for head know what to do to show potential
cocksucker that they are open for business.
Body language: Read body language.

If a guy is total covering up and turning away from you he is not interested. Let it go -- move on.. it is one cock you are not going to suck. Get over it.
In the open theatre you cannot expect privacy.

But you should be able to get sucked or fucked without having unsolicited hands groping at your cock.

You cannot expect to have people not look at you.

If you want total privacy ..go home.

Cruising around private video booths:

Generally if a guy leaves his door slightly open he is looking for some action.

My personal experience suggests that the guys looking to get services go into the booths and the cocksucker stay outside and move from booth to
booth until they find someone who lets them in the booth .

Glory holes are prime real estate.

Do not be a total pig and monopolize the stall for hours.

Respect your fellow cruisers and hope that they will respect you!!!!
