Public transportation going on strike can be seen as foolish because it inconveniences and disrupts the daily lives of countless individuals who rely on these services to commute to work, school, and other important destinations. It also reflects poorly on the reputation of the transportation workers and the overall industry, potentially leading to a loss of public trust and support. Additionally, strikes can have negative economic impacts on businesses and the local economy, as well as create safety concerns for those who may be forced to seek alternative, less reliable modes of transportation. **

Whether it's worth leaving the airport and going into the city depends on the length of your layover and your interests. If you have a long layover and want to explore the city, it can be a great opportunity to see some sights, try local cuisine, or shop. However, if your layover is short, it might be risky to leave the airport as you could potentially miss your connecting flight. It's important to consider the time it takes to get to the city and back, as well as any potential traffic or transportation delays. **
