Some people are a bit better at it, however it's still mainly a gamble. There are so many factors behind it. For instance,what Uber Eats or Deliveroo do today, we used to have about 15 years ago in Lithuania.You could call any taxi driver and say: 'I need a little service'.The driver then asked for specifics, how many bottles of alcohol,what type,etc.go buy it from the shop and deliver to your home.Everybody just assumed it and none had an idea how such a thing would grow into multibillion dollar industry.
