Doing security for bars

Q: Is it permissible to work events at a bar/ brewery doing security. They have nothing to do with alcohol. They just do crowd control and access control. Moreover the person works for the security company not for the bar. They have the contract so he gets called for events for ex: weddings, auctions, dinners, parties etc Most part is doing games at the air Canada Center for raptors and leafs and sometimes at the bar.

And the other question is I am currently a full time Imam in America and I do interfaith. There is a class coming to my mosque next week no the boys and girls will be coming together what do you advise me to do separate both of them or talk to them together?

Advertising online

Q:

(1) I wish to advertise online for a certain company. They will pay me for the advertising I place on the internet of their products. Before doing so, I have to enter in a contract with them that I will not use any copyrighted materials on a website I run. Else it would be illegal (in the eyes of kaffir governmental laws) and violation of our contract. Is it necessary to honour this agreement I may make with them? I consider copyrite to be not recognised in Shari'a.

(2) The agreement also has a number of other mundane clauses and conditions that do not have a Deeni implication like above. For example, the agreement states that I cannot advertise on a certain type of website, or give someone a link to their website via email. If I agree to their 'operating agreement', is it necessary to follow all these laws?

(3) If not, will I be sinful for dishonouring my 'operating agreement' contract with them?

(4) Similarly, will any potential income from this business operation be haraam or 'tainted' if I do not follow the permissible clauses of the agreement/contract?

Working in a place that sells pork and wine

Q: I am a student and working part time. I want to know that if I work in a place where pork and wine etc are sold and I would have to deal with these things, is it permissible in a non-Muslim country? In addition, I have tried my best to find a job that does not involve this stuff but either the pay rates were far below the minimum wage rate or I had no experience of that work.

Working in an accounting firm

Q: A person works in an accounting firm in USA where his main job is to do book keeping and monthly sales tax returns. He also does personal income tax and business income tax yearly. A situation arises where his boss ask him to fill out a client's previous three years business income tax based off estimation. The revenue will be reported accurately, however expenses will all be estimated to show a loss for the past three years. Is this permissible to do or no? Secondly, is it permissible to intentionally exaggerate expenses to reduce the amount of tax that will be paid to the government? Lastly, will it be permissible to estimate certain income and expense figures that are not available? Pertaining to the last question, even the best accounting system does require some level of estimation. First question is regarding the permissibility of the action. Second is that if this is 20% of his job, is his income halaal?  Some level of detail will be greatly appreciated. JazakAllah for your answer.
