假冒或危险的街头毒品
手法: 街头毒贩，常出没于市中心和红灯区附近，向游客兜售掺假或有害物质的假毒品，有时更是抢劫的圈套。向他们购买既有风险又违法。
如何避免: 绝不要向街头毒贩购买任何东西。这既不安全又违法，以这种方式售卖的药丸或粉末已造成过严重伤害。有人兜售时请直接走开。
Tourist scams in 荷兰 — and how to avoid them
These are the tourist scams Trzly has documented across 荷兰, grouped by destination. Each one is real, with a clear way to stay safe. Read before you land.
In 阿姆斯特丹
Full 阿姆斯特丹 guide ›自行车租赁损坏索赔
手法: 一些租车点会先拍下车辆照片，等你还车后声称车上原有划痕或车辆“被盗”，要求从你的信用卡或押金中扣取高额费用。
如何避免: 在口碑良好、正规经营的店铺租车，骑行前自己拍照留证，保留收据，并始终用店家提供的锁把车正确锁在固定车架上。
游客陷阱餐厅溢价
手法: 水坝大街及主要广场周边的餐厅用带图片的菜单和拉客的服务员吸引路人，随后以虚高价格提供平庸的食物，并附加意外的额外收费。
如何避免: 避开有员工招手拉客、每道菜都配图片的地方。往约尔丹或德派普方向走几条街，查看印在纸上的明码标价，选择本地人光顾较多的地方。
电车及人群中的扒手
手法: 小偷活跃于拥挤的电车、中央车站及热门旅游区，趁乘客拥挤上车或制造推搡混乱之机，顺手偷走手机和钱包。
如何避免: 将背包拉链拉好并背在身前，牢牢握住手机，在电车拥挤或有人碰撞你时格外警惕。只随身携带当天需要的物品。
In Rotterdam
Full Rotterdam guide ›Pickpocketing at Centraal, markets and on trams
手法: The most realistic risk for visitors. Thieves work the crush at Rotterdam Centraal, in the Markthal and busy shopping streets, and on packed trams and metros, sometimes using a distraction such as asking for directions or dropping something to lift a phone or wallet.
如何避免: Keep your bag zipped and in front of you, secure your phone, and be extra alert when a tram or platform is crowded or someone bumps into you. Carry only what you need for the day and stay aware in the busiest tourist spots.
Bike-rental damage disputes
手法: A handful of rental outlets may photograph a bike and later claim pre-existing scratches, or charge a large fee for a bike reported as 'damaged' or stolen, taking it from your card or deposit.
如何避免: Rent from a well-reviewed, established shop, photograph the bike yourself before riding, keep your receipt, and always lock it properly to a fixed stand with the locks provided. Ask up front exactly what happens if the bike is damaged.
Overpriced tourist-strip dining
手法: A few restaurants in the busiest, most tourist-facing spots near the main sights charge premium prices for average food, banking on the location and passing foot traffic rather than quality.
如何避免: Walk a street or two away from the busiest squares and the riverside, look for where locals and office workers eat, and check the printed menu and prices before you sit down. The same money buys much better food a short walk on.
Fake charity petitions and collectors
手法: Occasionally around the centre and stations, people with clipboards or official-looking badges ask you to sign a petition or donate to a 'charity', either to distract you for a pickpocket or to pressure a cash donation that goes nowhere.
如何避免: Politely decline and keep walking; genuine charities do not chase tourists for on-the-spot cash. Do not stop to sign anything in a crowd or hand over money, and keep your bag secure while you move away.
Taxi long-routing and no-meter fares
手法: A minority of street taxis may take a longer route or quote an inflated flat price rather than running the meter, especially with visitors who do not know the city or the fair fare.
如何避免: Use the official taxi rank or a booking app such as Uber, insist the meter is used in a street taxi, and check the route on your phone. For most trips the metro, tram or a water taxi is cheaper and just as quick.
