Ridiculous Coding Practices by companies you have worked for
prpon: I interned for a health care company where the lady in charge of my work had a Microsoft Access database with a single table.
That table had something like 500 columns.
I spent a week or so understanding and created a decent normalized relational database model.
I was not allowed to make any changes. The reason given was 'You will leave, who would understand and maintain all these tables'
