No this is reasonable. There is no reason he would be talking to the same people. Sure the same border agent can work incoming/outgoing, but not at the same tim

No this is reasonable. There is no reason he would be talking to the same people. Sure the same border agent can work incoming/outgoing, but not at the same time (not at any airport or road crossing I've ever been through). Border agents should know which side they're facing and which direction those people are traveling in. If they're not, they're incompetent.
