Pissed offffff

So took my daughter doctors the other day got there 5mins early the receptionist checked me in etc went through to the waiting room and waited, and waited then the kids started acting up so I thought let me check the time omg I've been waitin for 20mins.
Obviously not happy with that I went back to reception who told me dr was running late, I was like well if u knew that y didn't u bother to tell me, you saw me here wiv my buggy & 2 small kids why the fuck would u think id happily wait around for 20mins.
She gave me sum bullshit explanation omg I was sooo vex & the drs was ram & I cud feel my voice gettin louder I was like GET THE MANAGER!!
Manager apologized which made me even more vex omg I was soo vex I cud cry, I shuda cried & made them feel really bad.
So I had to end up waiting 30mins jus for my daughter to see a dr.
Now if you have toddlers you will know how frustrating that wait wuda been especially when they both wanna jump out the buggy run around bounce on chairs, dissapear, play up in the water from the water dispenser slide along the floor etc
Still pissed off about it, I shall be writing a lonnnnng letter of complaint when I find the time this week
