The cleaning staff won't envy your $6 bread if you're also spending twice as much as strictly necessary on your cleaning staff. That is, if you buy $6 bread instead of $3 bread, you should also be paying $21/hour to your cleaners instead of $10.50/hour.

If the judgment you fear is "this person values bread more highly than people", then just make sure you value people more than bread.

Don't peel the price tags off. They know how much they're paid. They can guess how much your bread costs, because poor people are required by economic necessity to know what consumer goods are worth, and often also how much it costs for market substitutes and DIY ersatz copies. If you buy a fancy leather couch for $12000, the maid will know that you could have haggled the salesperson down to $8000, and maybe also that the same factory makes a similar fabric-upholstered couch under a different brand name, and sells it for $2250, or $1500 if you rent a box truck and drive to North Carolina to pick it up yourself. $500 if you ask Shady McLoadingdock about "damaged goods". $350 if you also give him some of the finer varieties of cannabis grown in your state. Poor people build and upholster all the couches. They drive all the trucks that move them around the country. They work retail and sales in the furniture showrooms. They have to hustle for everything just to make ends meet. Don't think you can fool any one of them just by yanking off a price tag.

The only thing rich folks should be embarrassed about is assuming poor people are stupid.
