Example: "Come in for a spa and get a free steak rib at a local restaurant" sounds 100% innocent, but there is a small fraction of a percent chance that someone might think "But what about an offer for me, since I don't eat meat?!" In public relations, probability values get converted to a number of real humans, so PR staff has to be aware of this probability of everything they post (which is always nonzero). That of course doesn't mean it shouldn't be posted, but they shouldn't be surprised when they get 20 negative comments if 100,000 people see their statement. It's a tradeoff considering the gain of making a statement.
Twitter's post easily breaks this rule without much subtlety.
If this, coming from someone who doesn’t know you, does not sound offensive, what does?
