there may be some bad karma headed my way

I don't feel very good about myself right now.

I did something completely out of character.
Lost my temper.

A few weeks ago, I'd bought a couple of  lightshades to put up in the flat.
From their available store stock.
 (no ordering required)
Pretty things, one for the kitchen, one for the lounge.
But I couldn't fit them and returned them.

Then I chose a simpler pair of lightshades from their catalogue.
The store had to order them in, because their usual stock is quite fancy stuff
and what I'd ordered was just plain coolie-hat shaped, brushed nickel outside, white inside.
Metal shades.

But I couldn't fit them to my fittings.
So today I went there after work to return them.

The manager said he was sorry, he couldn't keep ordering things that people didn't want and couldn't refund my money.
Keep ordering?  As far as I know this was the only time I'd ordered anything.
I suspect the real problem may be that the plain coolie-hat shades probably couldn't be re-sold in such an upscale "decorator" shop.

Anyway, very suddenly, unaccountably, inexcusably, I was upset. And angry.
I stormed out of the shop, slamming the door as I did so.
I immediately felt terrible at what I'd done, and felt worse when the manager stormed after me and told me my behaviour was ridiculous. 
As if I didn't already know that. * 
(Maybe he'd had a bad day?)

I apologised, (sorry, sorry, sorry, over and over), then kept walking to the bus stop.
I felt so bad about myself,  I cried all the way home.
(Tried not to, but hid my face behind sunnies and a hat).
As soon as I walked in my door, I looked up the phone number of the shop and phoned to apologise.
The manager wasn't there, but I left my message. The girl on the phone was very nice.

The problem with my batten-fix light fittings is the black part that holds the globe has been pushed a little too far into the part that's screwed to the ceiling, so not much of the thread is showing.
 I can't adjust that, (not without calling an electrician), so when trying to fit a lightshade, the "skirt" won't screw back on to hold it.

(I needed much thinner, plastic lightshades, (or none at all).
As luck would have it, last weekend,  I spied a couple of these old style plastic shades on a roadside dump.
I brought them home, washed them, and tried to fit them. They went up beautifully.
I now have lightshades.
Free lightshades.
Of course now I'm still stuck with two expensive metal shades that I  have no use for).

*Worse in my eyes, because I was in uniform, so putting forward a poor image of the store I work in.
