I keep doing this!
I go shopping because I need something new, spend a couple of hours trailing the shops hating everything. Then when I realise it's almost closing I get that feeling that passes through nightclubs near the end of the night, and desperately grab hold of the least-worst thing I can see and get out of there.
I need to find places other than the usual highstreet haunts to get my garb.
Not that such other places exist round here.
