The following things have gotten me labeled as "cheap":
Oh this will be good...
“Asking to take leftovers from fancy restaurants”
Hmm, maybe depends on the restaurant...
“Buying toothbrushes at the dollar store instead of the pharmacy”
You can buy toothbrushes at the pharmacy???
“Not having a flat screen tv until 2011”
We got ours 2015, I think
“Not having the latest and greatest cell phone/computer/tablet”
I usually buy a top device and then keep it until it breaks. Laptop from 2011, phone from 2007.
“Cutting my own hair, doing my own pedicures”
Depends on the haircut. My wife has a ponytail, no need to go to the barber for that
“Cutting our grocery spending by eating low cost foods like beans and rice”
For us it’s just normal to eat rice and potatoes
“making our own granola and yogurt”
Ok seriously where I live people would admire you for this. Just say it’s a lifestyle health thing, don’t mention the cost savings.
“Mending my clothes instead of buying new clothes”
See above
“doing our own house repairs instead of hiring everything out”
Again, but sell it as manliness or something like that
“Staying at normal hotels/apartments instead of luxury resorts while on vacation”
We spent all our vacations at youth hostels last year, so there’s still room to be cheaper. Wait, probably better to not mention that to your friends...
Overall, I don’t understand why your friends care about these things. Do they think they look bad by association?
