Why does the woman make the phone call?

M:   Good morning,   this is Kevin Johnson.   What can I do for you?
W:  Hello,  manager.  Can’t you do something about the service in this hotel?
M:  I’m sony,  madam.   What’s the problem exactly?
W:   My breakfast,   that’s the problem.   I ordered a full English breakfast from room service at least half an hour ago.  I’ve telephoned them three times but my breakfast still hasn’t come.
M:   I see.
W:   I’ve got an important meeting at nine o’clock.   And now it seems I’ll have to go there without breakfast.   Really I don’t think this is good enough.
M:   I’m very sorry,   madam.   You ordered breakfast half an hour ago and you phoned three times since then.
W:  That’s right.
M:   I’m really sorry about this.  You should have received the breakfast no later than ten or twenty minutes after you ordered it.
W:  That’s what 1 thought.
M:   The problem may be that they are short of people in the kitchen recently,   but I will look into this myself.   Full English breakfast,  was it?
W:  Yes,  full English breakfast.
M:   Very well,   madam.   I will bring it up to your room right away.
