1. Artem owns a business with 200 employees including Bryony, Charles, Devi and Eytan.

Artem's bicycle

is stolen from the bike shed at his business. On Monday he sends an email to all his

employees:

Please help me look for my stolen bicycle. It is only worth 20 but is of sentimental value as it

belonged to my Dad. I will pay a reward of 200 to anyone who returns the bicycle to me or

provides information that helps me locate it.

On Wednesday he decides to forget about his old bicycle and to buy a new one at the

weekend and so he pins a notice on the bike shed stating that his offer of a reward for the

return of his bicycle is now withdrawn. On Friday afternoon he also sends an email to all

employees stating that the offer of a reward is withdrawn. Consider the following alternative

circumstances:

a) Bryony, an employee, is ill on Monday and Tuesday and does not come into work. However,

she goes for a short walk and sees Artem's distinctive bicycle on a rubbish dump. She then

returns it to him on Wednesday morning.

Advise Bryony.

b) Charles is a new employee and is keen to impress his boss. He takes Tuesday and

Wednesday as holiday and searches for the bicycle which he finds for sale in a second-hand

shop. On Thursday he goes into work and tells Artem where it is.

Advise Charles.

c) Devi learns from Freddie, a colleague, on Thursday about the notice Freddie has seen on the

bike shed withdrawing the reward. That evening when leaving a pub Devi sees Artem's bicycle

in a hedge and returns it to him the following morning.

Advise Devi.

d) While walking to work on Tuesday morning Eytan sees the bicycle outside a shop where the

thief has left it. He is riding it to work when he is overtaken by Artem in his Ferrari who shouts 'I

hope you are not after the reward, I've changed my mind'. Eytan takes the bicycle to work and

gives it to Artem, who refuses to give Eytan any reward.
