1) Builders really wolfwhistle (and are jerks).
2) Tesco's self-service machines are (not quite) subtly designed to maximise the number of coins you get in change.
3) Some people only recognise me if I have a beard and my hair long and down.
As to 1) that would be twice in one week and it wouldn't be so insulting if they were laughing like idiots at the same time... if they weren't going to be around for the next few months I'd already have complained to the company they work for.
As for 2), Tesco's self-service machines were apparently designed by a Dane and built in China and do not give fifty pences or two pound coins as change; "no biggy" you might think but it means that the number of coins yet get from the machine is higher and coins of a smaller denomination at that. Combine that with the fact they are designed to give you as even a number of coins as possible means that they will give you 50p in change as two twenties, one five, two twos and one one pence coin... making that six coins instead of three (assuming no fifty pence pieces) or one (assuming fifty pence pieces exist - which they do). I am also suspicious as I have never had a ten pence coin out of a machine so I wonder if they also either don't give them out as well or try to get rid of the coins they have most of and so very much prefer to give out a five, two twos and a one pence piece than a single ten pence coin... this would be because people prefer to give the machine lots of shrapnel than bigger coins so then they start trying to get rid of it all again.
And in the case of 3) the guy at the chippy recognised me from a few years back when I had long hair and a big beard despite the fact I've been going there time to time before and he's not recognised me; but my hair was up and (to my shame) my beard has grown out a bit at the moment... need to get around to shaving it! Weird! :)
So the take away is people don't always see what is infront of them, either way if they are a builder they are probably jerks or idiots and Tesco's has gotten it's third strike from me for anti-society behaviour; contracts that mean suppliers have to buy back goods not sold even if they are now past being sellable, failing to pay millions of pounds worth of bills owed to small companies who don't have the resources to fight them for it and some, many of whom have gone bust (explaining why there is less and less variety of things on their shelves over the years) and nickle and dimeing customers over the weight (and maybe amount; how many people actually count their change, especially when it is a pile of coins?) and number of coins of change.
Gonna watch Off Topic while eating my chippy (saus supper with salt and sauce *yum* :) now to make myself feel better :)
