People are often bashful about being caught at their local bar drinking when they should be elsewhere, e.g., with their families. Sometimes people looking for bar regulars will call and ask if the person they are looking for is at the bar. But --- here, the person is an escaped prisoner, and the person calling would be the guard looking for him, so he has extra incentive to not be found.
