Safety and Warnings - London
The transportation system can be quite confusing so it is important to be extra careful about the departure timings of various trains / tube and coaches.
The places have similar names so first time visitors may find 2 different areas with the same name. In order to sort out the confusion, be prepared and ask help from locals who can guide you to the correct location.
The most puzzling example is Victoria station. The coach station is just at few minutes walking distance from the main train station and quite different from Victoria station, which is a bus station. Visitors often get quite confused by this.
Parking is not free and visitors are required to pay the charge before parking their vehicle. Failure to pay leads to difficulties.
Do not buy any eatables from street vendors. The food can be quite unhygienic.
Many of the vendors are illegal as well, so, the wise thing to do is visit good restaurants to enjoy the delicacies.
