Reminds me of a colleague implementing "emailRecipients" as a field in a singleton service. The first online order got an order confirmation mail, and when a second online order came s/he also got their confirmation mail (the field just grew and grew...).

To be fair singletons are pretty useful. You just have to understand that they're not made for mutating state.
