Your opinion, with or against? How would affect displaying religious boards in sales showrooms, head office lobby and personal desks ?

First of all, it is not necessary to show religious boards in an office, however, it may also be used for certain reasons, e.g., to attract customers from a particular community, like if a company is selling food stuff, they may use the HALAL word to attract Muslim community, just like Japanese has started using Halal food and have introduced prayers rooms at their airports to attract Muslims;  Than, many people believe that having religious boards displayed on different locations can protect them from evils and their business could flourish with its blessings.  For example, many Christians use cross signs as a blessing for them.
