Traveling is a current very popular leisure activity. To relax and discover a different culture and foods.
When people go on vacations to another city or another country, they book an hotel.
And hotels can be very expensive depending on how trendy and touristic are they located.
I wonder how people never realised how non-hygienic is to sleep in a hotel's bed..sleeping in a mattresses were hundreds or thousands of people slept there before...sweating there, having sex there...urg!.. and paying expensive for that...not even talking about the pillows..
I want to believe that in the future, people will realise how non hygienic that is and hotels will change their cleaning methods.
