My father in law has an easy pass tag as he uses the East Link a lot. Recently my mother in law was coming back from a day trip to relatives in Dundalk and Mrs Bloggs was with her. The MIL made straight for the port tunnell and, given that it was the afternoon of a weekday, Mrs Bloggs queried this as she said it would be expensive.
"Not at all" the MIL said. "Its free. I use it all the time."
When the barrier shot up at the end of the tunnell the MIL smiled triumphantly.
