My friend's father takes the subway to work, which is a convenient and efficient mode of transportation for him. He usually boards the train at a nearby station and travels with other commuters to his workplace, which saves him a lot of time and money on commuting. Sometimes, he might encounter delays or overcrowding during rush hour, but overall, he finds the subway to be a reliable and affordable option. He enjoys the ride and uses the time to catch up on reading or respond to emails. In short, taking the subway to work is a practical and enjoyable experience for my friend's dad.
