Agent 47 arrives by boat at a pier on the eastern side of the map. Atop the nearby staircase there is an embassy waiter on a cigarette break. Although generally passive, the waiter can become alarmed upon seeing a weapon (such as the AK-74 that is possibly still in your possession from the previous mission). If this occurs, he flees towards the nearby embassy and alerts a guard, who comes running to investigate (this also causes the guards to be on the lookout for "a suspicious bald person.") You can avoid alerting the waiter by either dropping your non-concealable weapon at the bottom of the stairs, or quietly walking/sneaking in the vicinity while carrying one. Note that there is little reason to bring a non-concealable weapon unless you plan to attempt a gun-blazing approach for this mi
