Showing good character when working among people

Q: We are a group working together on various assignments. Lately, I started having fights with a friend who is also a co-worker due to his mood swings. This person presently does not like me due to few issues that took place between us. Please could you provide an emergency wazifa to remove hatred and anger from this person's heart for me so that our friendship can once again be restored.

Accepting a different currency from a customer and exchanging it for a better rate later on

Q: I work at the airport at a car rental. Now if a customer comes and wants to pay in Euros but we accept only Dinars, to make his work easy I take the Euros from him at the current exchange rate at the airport knowing that the exchange rate will be better outside in the city. So I accept those Euros and use my Dinars to give to the company and later take those Euros and exchange it in the market at a better rate for myself or sometimes I wait for an even better rate. Is this money halaal? 

Husband forcing wife to leave the home to work

Q: I am dentist but not interested in working. My only purpose of marriage was to serve my husband in Islamic ways, obey him and stay with his family. But his demand and wish was for me to work. He said that it doesn't matter if I go outside and remove my burkha and work. It doesn't matter if I have to discuss professional services and cases with male doctors. It doesn't matter if I have to travel alone on buses and trains or for long journeys. He just wants me to work which pleases him and makes him proud in front of friends and society.

He doesn't consider my will nor understands my view for not working. I told within a few months that when we have a baby inshallah then responsibilities will increase and I want to be at home and raise the child and serve him and take care of the home. Though, he is financially fit and earns a good salary, he and his mother always taunts me for not wanting to work.

After so much mental stress I had a miscarriage and fell very ill and decided not to work to avoid such nusiance. I was so weak and was planning for pregnancy and I told him when my bus stop comes, please come early and pick me up and while departing, he should hold my hands because I was afraid of losing a baby agian, but he never came early neither stood at the stop. Sometimes I felt like I should catch hold of the conductors hand who is non a Muslim and na mahram to avoid falling and discomfort but again held myself back because it woulld be a sin if I do so? In such situations what should I to do?
