I honestly don't know if I was or not, so any opinions welcomed, and I will suck it up if I was 
I work for a music examining board and we are at the time when I have to collate all the exam entries. It's part time, seasonal work, but when it comes in, it is hours of work to a very tight deadline.
I took the DDs up ice skating this morning. The really needed not to miss it as DD2 has a couple of competitions coming up. But I really needed to work. So I sat in the leisure centre coffee shop with a coffee at a big table, spread out all my paperwork and got on with it. It was pretty early morning so the place was virtually deserted, masses of empty tables and just a handful of other people there.
Halfway through some complicated adding up (it's literally thousands of numbers) a lady came and sat at my table, opposite me. I thought it was strange because mine was one of the only occupied tables and most people choose a vacant one. She kept making sniffing and sighing noises. Under normal circumstances I might have smiled or asked if she was OK, but I was trying to get this work done.
After a while she got up, got a drink of water, sat down, shuffled some of my papers over and put the drink down. She started the noises again, trying to get my attention, I think, and I did start to think at this point that she might have some sort of special needs, though you wouldn't have known looking at her. I just completely lost concentration in my adding.
About 5 minutes later a man who obviously had Downs Syndrome came over with a coffee on a tray. He said a cheery hello to me and proceeded to also sit down, putting the tray on my paperwork.
At this point I said very nicely "I'm really sorry, but would it be OK if you sat at a different table? I am really very busy."
They looked terribly hurt and got up. A lady a few tables over I then noticed was obviously looking after a whole group of people with learning difficulties. She said "sit here, you're welcome at this table, " and glared at me like you wouldn't believe. Then she sat and shot me looks for the next half hour.
I felt rotten afterwards. I know that in a different cicumstance that could be me or a family member. I really hadn't meant to upset them. But on the other hand, I was at one of the only occupied tables, I asked very nicely, and I didn't think it was unreasonable to expect to be left in peace when the place was so quiet.
So, was I being unreasonable? Did I deserve the glares?
