Bolded by me.
I don't think it's a stretch, that there is a reason why Lynn's bankcard statements went to her work place address, considering the plethora of corroborating claims that Dawson was meaner than mean and particularly incensed about Lynn earning her own money ( and not having to beg him and produce favours for it, like Joanne had to ) .. and deeply insulted by Lynn having her own bankcard, over which he had no say, nor control nor oversight, nor input..
The bank must have been instructed by Lynn to send statements about her own account to her work address, thereby in one swoop cutting Dawson completely out of all interference in her business. I don't think the sending of the statements NOT to her home was an accident. Maybe even the bank suggested it, after some discussion with Lynn.
It would be no skin off the banks nose, no problems, and Lynn would have avoided what it is reasonable to assume would be a long running nagging , threatening, abusive volley about the Bankcard , a daily shaft, so she deprives him of the evidence of it's availability to her. She doesn't have to deal with interrogations about what she bought with it, for whom, why, when, where, should she have, and so on.
All of this must have been tedious in the extreme for Lynn, and I think, perhaps a forewarning of just how ruthless and savage he could be, although for Dawson it would have been terrific, some hook to hang his nasty hat on.
