The Lunch Lady (well technically dinner)

Wednesdays are a long day for me.  I am at school all day literally.  I do not get home until everyone is in bed.  So I have to eat lunch and dinner at school.  I am going to try to be really diligent and pack my food but man, that is hard too.  Last Wednesday I gave in and decided to go and buy my dinner at the Student Life Centre where they have several different vendors.
I stood in line, shimmying to the left with the rest of the students, waiting for my turn to order. Admittedly the tired part of me was staring off into space and not paying attention when the "lunch lady" spoke to me:
"Excuse me sir, excuse me"
I snapped out of my daze and looked to the guy to my right, had the "lunch lady" just skipped right over me!  How dare she and I turned to her to utter my dismay over being forgotten when I realized that she was looking at me.
"Sir??"
"Oh I am sorry Ma'am I don't have my glasses on."
Now I do have short hair but without glass I look like a man?  I wear glasses, I can still distinguish gender.
The gentlemen beside me jovially said to the "lunch lady"
"Oh oh, now I think she may need therapy" and smiled at me.
Damn straight! I have just started school as a thirty something in a twenty something word and I do not know very many people and my confidence levels are at their minimum and I just got called a man!
The "lunch lady's" bizarre response was this:
"Well she could talk to my husband, he is a therapist and great listener, well actually he is a welder"
HUH??? and of course because I am so eager to please and avoid confrontation, I say:
"Oh, mine too."
Shit I am going to be friends with the "lunch lady" before I even get my dinner.
I watch the "lunch lady" get my dinner, put it on a plate ad begin to hand it to me and I think I am off the hook and this traumatic blow to my self esteem is over, but just as she hands me the plate, she turns to the guy to my right and says:
"Oh so you are a welder?"
"No!"
Poor guy, not that I would have been insulted, he was cute, but he was just waiting for his dinner and next thing he knows the "lunch lady" has him married to a guy and welding!
Needless to say my dinner did not taste as good as I had hoped that day.
