Is it permissible to pay bribes to officials to facilitate transactions and avoid the closure of the exhibition, knowing that non-payment leads to the rejection of applications and the favoritism of competitors who do pay?

It is permissible to pay money to obtain deserved services, and this is not considered a bribe for the giver, but rather a bribe for the recipient. However, if the person is not deserving, or if someone else has a greater right, then it is a forbidden bribe.
