Second conversation about toilets this year

So seems I can't go anywhere without raising suspicion. I've been working in the city at the North Sydney store. I go to the bathroom a lot due to lack of work available and because I don't like blowing my nose in front of people and I just got over being sick. The following is a conversation that happened after I came out of the bathroom today:

Lady: Is there a reason why you're always up here?!

Me: Um...the bathroom.

Lady: Why?

Me: I've been drinking a lot of water and I need to go a lot.

Lady: Oh do you work here, do you?

Me: Yeah...at [graphic design place].

Lady: On the GROUND floor?

Me: Yes...

Lady: Don't you have your OWN toilet??

Me: No...

Lady: Oh well I was just checking, just incase you were trying to case the place.

Me: Um...okay, thanks.

1. Lady, don't you have a job? Why are you at that damn reception desk so often that you notice how often I come out of the elevator? Quit chatting to the receptionist and do your effing job, you nosy douche!

2. Why? WHY?! Why else does one go to the bathroom? Either I need to pee or I need to pretend I need to pee so I can do something productive with my life, geez. Is it really my fault there is little or no work for me to do?

3. Nope I don't work here. I'm a bumb. I dress up in my best clothing, do my hair and my makeup and travel all the way in here from Penrith just to use your "lovely" bathroom. Which by the way, isn't half as classy as I thought it would be.

4. Yes. The groundfloor. Do you know any other places that there is a [graphic design] store in this building?

5. If [graphic design place] had a toilet do you think I would walk out of my store, enter the main doors of the building, through the corridor, up two storeys in the elevator, through the lawyers reception area, up the hall way and around the corner just to use the less than impressive toilet? No. I think I would just use the toilet in my store, dickhead.

6. One of these people are going to have to realise that I'm not a bad person. I am NOT up to no good. And they better believe it before I go postal, otherwise they'll make their worst fears come true. I'm sick of being treated like dirt. I am 20 years old, I am nearly finished my degree, I have two jobs, I am a part time carer for my older brother, I pay my taxes...what more do I have to do to get some respect around here?
