A few errors in Retail Etiquette:
The customer service person should have apologized. Next she should of asked if you'd like refund or replacement bacon making those options clear.
Food goes bad sometimes in the best or markets, it's an inherent risk. Are you really entitled to "pain & suffering" for Green Bacon, I tend to think not. I feel this falls under "Poo-Poo happens" sometimes.
If green bacon was so morally offensive, you should have informed her of your emotional distress thus affording her an opportunity to make you whole again by either offering you additional bacon as compensation pain & suffering or referred you to a management person empowered with the authority to approve additional bacon. I think it goes without saying that the stores best interest would be served by not creating a pork product incident that would inevitably reach a world wide audience on a aquatic plant hobbyist website.
You breached established retail protocol by not expressing the full extent of the drama you experienced due to the green bacon in question. That was complicated by your assumption that 50% additional bacon would resolved the matter without acceptance of terms by the markets representative.
It's sad state of affairs when such total breakdown in protocol occurs. Hopefully lessons were learned.
Had I been in this situtation, I think I would have taken the bacon to the service desk and asked for the manager. I would have told him I bought this the day before and show him the offending bacon and state, "I can not eat this Sam I am!"
