I have never used Metamask since the ethereum gas fee increased. You can see the difference in gas prices when using Metamask and try using another wallet to make deliveries, ethereum gas fees are expensive because the whole network is busy due to DeFi transactions.
Having a little ETH for fuel is not a good thing, it is better to hold tokens and increase the amount of ethereum to make transactions faster than sending tokens with a small amount of ethereum gas fees and will result in failed transactions
