Stop in for a cup of coffee

remember I got new tires on my truck several weeks ago?? well, my "appointment" this morning was to have a tire replaced ..between 45-50mph there was a bad wobble - shake your liver bad - they had tried 4 times to re-balance it - I called on Thursday and insisted that it be fixed - no more BS... one new tire later - smooth sailing.
Nicely done. . Did you threaten them bodily harm?
