LRG T-shirt [work in progress]

This post is long overdue. I originally purchased the LRG "a revolutionary clothing company" t-shirt from a retail urban clothing store (ie, hip hop shop) on the infamous Washington Avenue strip of South Miami Beach.

I have an extensive collection of t-shirts and know how to take care of them.  After only the first wash, this is what began to happen

Miami-Dade Expressway Authority

I just got hosed by the Miami-Dade Expressway Authority, better known as MDX.  I was sent a separate invoice for the multiple times I drove through their electronic toll booth(s) during the month of August 2010.  These toll road
ways do not provide advanced warning of one's inability to
pay at a booth, therefore one can not take another route before
they're already captured on film and billed for a PREMIUM 
toll fee.  This fee is charged as a result of not having a "Sun Pass" and requiring their 'system' to bill by mail.

 They did respond recently to my inquiry:
 "Unfortunately we are not able to credit your account. We did received a payment for $5.50, for invoice # 100171540 issue on 9/2/10, Them we send invoice # A100303749 on 10/14/10 for $3.40 due on 11/4/10 it escalate to S100432963 on 11/22/10 due on 12/13/10, and it escalate
to V110740122 on 1/25/11. Our system electronically
escalate invoices adding additional late fees if we do not
received payment by the due date. We do apologize for the inconvenience this has brought unto you."

Is this practice of entrapment acceptable?  You decide.
