(TMZ) - Sean Combs is a corporate tyrant who had the audacity to force an unpaid intern to ... gasp ... GET COFFEE ... this according a new lawsuit obtained by TMZ. 

The ungrateful person behind the suit is Rashida Salaam - who claims she took a gig as an unpaid intern for Bad Boy Entertainment from January 2012 to May 2012 and couldn't BELIEVE the kinds of work they had her do for free: 

- answering telephones
- getting lunch and coffee for paid employees
- making deliveries
- gift-wrapping presents
- decorating the office during holidays

Just torture ... 

Salaam probably has a real case, thanks to recent changes in the law regarding unpaid internships (no more free labor for course credit) ... but she's probably hurting her chance at landing a full-time gig with the company by filing the suit. 

TMZ reached out to BBE for comment - so far, no word back.
