When checking in at a motel or hotel, you can also try throwing a water bottle under the bed to test it. Throw the water bottle vigorously from this side of the bed. If there are people or obstacles underneath, the water bottle will not roll out. In that case, you can check under the bed yourself or ask someone to accompany you or contact the receptionist to check together.
If there are no obstructions under the bed, the water bottle will easily roll from one side to the other. At that time, you will feel more secure about the safety of the room.
Bending down to check under the bed as soon as you enter the room can make you surprised and embarrassed if there is someone lurking inside. On the contrary, throwing a water bottle under the bed gives you more time to prepare. If you detect anything unusual, you can quickly leave the room without having to bend down to check.
