Honest & Professional
Honest and professional is how I've been described this time, Ill take that.
"These guys are an honest and professional business. I left the house with a key in the back of the door whilst in a hurry and couldn't use the other key to get back in. The locksmith was at my address within 30 mins, despite it being a bank holiday Monday and I was back in within a minute. I asked about a finger lock so I couldn't make the same mistake again and he fitted that within 5 minutes. Cost me half what I was expecting which included a new fool-proof lock and 3 keys."
Keep it good, keep it Honest & Professional.
