An act of gift’ and ‘an act of bribe

‘A gift is a bribe if you can’t eat, drink or smoke it in a day’.

‘If you think that your offer of acceptance of a particular gift would have grave or merely embarrassing consequences for your  company if  made public, then the gift should be considered a bribe’.

‘Bribe can be said to be a substantial amount of money or goods offered beyond a stated business contract with the aim of winning an advantage in gaining or keeping the contract ’.

Here ‘substantial’ means that which is sufficient to distort the judgment of a typical person.
