Do thing ahead of time

am an 007 fan,I heard that newest movie of 007 is playing now.So this afternoon I told my wife to go to the movie together.

At 7:00 PM,my wife and I arrived the cinema,’It may begin any time ’ I
said,’It may have begun’,my wife answered.I hurried to the ticket
office ‘May I have two tickets?’ I asked,’We’ve sold out’ the ticket
seller answered.’What a pity’ my wife exclaimed.At that moment a man
hurried to the ticket office,he said ‘Could I return these two
tickets?’ ‘Sorry,’the ticket seller said ‘The movie will begin in 30
minutes,you can’t return it.’ I went to the man at once.’Excuse me,are
those tickets for 007?’I said.’Certainly’ the man replied ‘Do you want
them?I can get you a discount’. ‘Okay,that’s great ,why not’ I said.

So we saw a great movie and have a great night.But this thing give
me a lesson,that I may as well book the tickets ahead of time.
