What are some cases where the police have reasonably detained a man in front of a bar where he was sitting on the curb?

The People also cite People v. Shoemaker, supra, 16 Cal.App.3d 316, 93 Cal.Rptr. 921, where the police were held to have reasonably detained the defendant in front of a bar where he was sitting on the curb. At the request of the police, the defendant then voluntarily led them to an automobile in which, according to defendant's story, he had arrived at the bar. When the party arrived at the car, which was about 75 feet from the initial point of confrontation, defendant started to shed marijuana. The court held that this voluntary act was not a response to improper police conduct.
